Oregon State University online CS degree eCampus program review and recap

In this article: my review of Oregon State University’s online post-bacc CS degree program, which I attended for 3.5 years, starting in September 2016 and finishing in June 2020, completing 15 courses with a 3.9 GPA and graduating with my second bachelor’s degree, a Bachelor of Science in Computer Science.

Yay! Being done is a great feeling. Pictured: my new diploma surrounded by the books, notes, and worksheets that were my BFFs during this program.

First, I’ll answer the most frequently asked questions I was asked while in the program:

  1. Yes, the program is completely online – the coursework is unlocked weekly in the online portal known as “Canvas”, you take tests online with a proctor supervising you over webcam the whole time, you submit coursework and get your grades online
  2. No, it is not self-paced – quarters are 10 weeks long, deadlines are firm barring exceptional circumstances (I never pursued an extension but they exist for those who can justify the need for one)
  3. But you can vary your pace through the program, such as taking 1 class a quarter to go at a slower pace and leave more time for the rest of your life, or taking 2-3 classes a quarter to get through the program faster (more thoughts on class pairings later in this article)
  4. You can take quarters off – I took a few quarters off here and there for things such as moving cross country and having a baby
  5. Yes, you have to already have a bachelor’s in some unrelated field – it’s a “post-bacc” program, so your first degree entitles you to skip all the gen-ed classes you’d normally need to do
  6. It’s still a normal bachelor’s degree on paper and the degree does not call out the “online” nature of the program in any way (you can see the diploma I received at the top of this article)
  7. Yes, there is a decent degree of “self teaching” in the program – at a high level, the courses give you problems to solve and they usually provide lectures and readings to guide your learning, but you’ll be on YouTube, Stack Overflow, experimenting in your own codebase, etc. to find answers and a deeper understanding than the course materials alone give you.
  8. Yes, it was still challenging (and I learned a lot) even with prior industry experience. I came into this degree with about 2.5 years of web development experience and prior to that, a bootcamp, and I still learned a ton from most classes. Previous experience will give you a small advantage, but there’s still a ton of work to do and problems to solve that take time and effort.
  9. Yes, it requires sacrifice – there are many things I missed out on during the last four years because I was busy with school, which dominated evenings and weekends.
  10. Yes, it was an excellent experience – I learned so much and rounded out my CS knowledge in ways that my bootcamp and industry experience had not.

Computers have been my passion since I was a child, and completing this degree meant a lot to me. It formalized something I’ve explored via hobby projects, game mods, my own little websites, etc. since I was a kid.

My favorite resource for learning more about the program is r/OSUOnlineCS. I lurked here for nearly a year before I applied, and visited frequently while in the program.

About me (and some encouragement for other “non-traditional” students)

I want to write briefly about being a “non-traditional” student because that’s basically who this program is for: students who already have an established life and commitments outside of school.

Returning students usually have at least a couple reasons why they think they can’t go back to school – they’re “old” (over 30, or 40, or whatever), they have children, they have a full-time job, etc.

I check all of those boxes – I’m almost 37, I had two babies while I was in the program, I worked full-time for part of it, I relocated cross-country, blah blah. If this is you, with all these existing demands on your time, I just want to say: it is possible! It is hard but it is possible.

I met quite a few other parents with full-time jobs on my journey through the program so I don’t think I am unique, just disciplined and willing to work hard. If this is you, too, don’t count yourself out just because you have other things going on in your life.

My path through the program

Here are the classes I took in the order I took them, along with links to my reviews on each class.

I put a ★ next to my top three favorites.

  • Fall 2016: CS161
  • Winter 2017: CS162
  • Spring 2017: CS225
  • Summer 2017: no class
  • Fall 2017: CS261
  • Winter 2018: CS325
  • Spring 2018: CS271 + CS361
  • Summer 2018: CS290
  • Fall 2018: no class
  • Winter 2019: CS344 + CS340
  • Spring 2019: CS475
  • Summer 2019: no class
  • Fall 2019: CS372 + CS362this was a punishing schedule, I do not recommend these classes together
  • Winter 2020: CS492
  • Spring 2020: CS467 ★

OSU regularly updates and revamps the courses, and some of these courses were revamped since I took them.

The most notable (and controversial) change was the switch from C/C++ to Python in the foundational classes. I took the C/C++ versions of 161, 162, and 261.

I think this was a good change. While I appreciate the experience I got with pointers, memory allocation, and a relatively “low-ish level” language, sometimes it felt like debugging C got in the way of learning the higher level concepts the courses were trying to teach.

What to expect from OSU’s online CS program

Pacing and scheduling

Classes follow a strict schedule. Each week, usually on a Sunday, a batch of lectures, worksheets, projects, quizzes, discussions, etc. unlocks. Most classes have a “late work” policy you can invoke (once or twice) if you need an extra day or two, but this is not a self-paced program. Deadlines and exam windows are generally strict.

The workload and time commitment varies a lot between classes. The OSU CS Course Explorer is a tool I made to help students determine which classes to pair and which to take alone. It scrapes its data from the survey hosted on r/OSUonlineCS. You can also search the OSUonlineCS subreddit for tips and advice from other students.

At any given time in the program I was either working full-time with a baby, or caring for two children while working my way through the courses. I frequently alternated between one class a quarter and two classes a quarter.

When I took one class at a time, I felt like I was making glacial progress towards the degree but I also had room to breathe. I could dig into each assignment, do extra credit, work on side projects, or spare a few days for an illness or a short trip somewhere. I even went to Disney World for three days in the midst of CS225! :)

When I took two classes at a time, every week was the time management Olympics with no room for slop. I started assignments the moment they unlocked and made every minute count, but the sheer workload guaranteed the two-class quarters were brutal. I lost my 4.0 GPA the first time I attempted two classes at the same time. It was exhausting, but… faster progress!

Classes to take alone

I realize there are financial aid and “I want to get this over with” reasons to take two (or more) classes at a time, but my personal recommendation is that these classes benefit from being taken alone due to their difficulty, time-consuming nature, and/or overall importance to one’s CS education:

  • CS162 Intro to Software Engineering II – insane workload and challenging topics, but I took the C version so maybe it’s not quite so unforgiving now
  • CS325 Algorithms – most challenging course of the program, it dominated my life for 10 weeks
  • CS261 Data Structures – high workload and challenging, especially when it was taught in C
  • CS271 Computer Architecture and Assembly – high workload and challenging subject matter
  • CS467 Capstone – it’s your final project, give it (and your group) the time it deserves

Classes to take with other classes

These classes were lighter weight or just generally not so programming heavy. A coding problem can occupy me up for hours as I investigate and trial-and-error my way through it, but I never get stuck like that when the task is just to write a document or forum replies.

  • CS225 Discrete Math – challenging but manageable
  • CS361 Intro to Software Engineering I – mostly a writing class
  • CS290 Web development – relatively light workload
  • CS340 Database – a very entry-level look at SQL plus a final project you can do the bare minimum on if you are so inclined
  • CS3344 Operating Systems – the projects are huge but they’re manageable, topics aren’t exceptionally challenging
  • CS475 Parallel Programming – well-scoped assignments, evenly paced
  • CS492 Mobile Development – predictable workload

Obviously, your mileage may vary – and courses get revamped every so often, too, so my opinions and experiences will become less relevant over time. (This was written summer 2020.)

Exams

Most classes have some sort of big test to take at some point. Some classes split this up as a “midterm” and a “final”, some require it to be proctored (supervised), some allow open book, and a few don’t have any kind of big tests at all. At one end of the grading spectrum are classes that treat exams as the bulk of your final grade, while others weight their exams so lightly you can basically fail them. Every class is a little different in this regard.

Before doing this degree, I was never the kind of person who studied for exams. I usually just winged it and did okay, but the OSU classes demanded it. Flash cards, practice worksheets, practice exams – I did them all, and usually managed a B or better on midterms and finals.

Proctored exams are no fun but they help ensure the quality of the program’s graduates. A proctored exam is taken either at a local test center (if you live near a community college they may offer proctoring services) or online with a service such as ProctorU on your usual computer. The overwhelming majority of students seemed to be using ProctorU.

For the first half of the program I took my exams in person at a community college branded testing site near me. The big advantages with an in-person testing site:

  • a dedicated testing environment where no one is going to come along and ring your doorbell mid-exam
  • you get to use scratch paper instead of a whiteboard

ProctorU makes you use a whiteboard, and it’s small so you have to have to wipe it every few problems and can’t easily refer back to previous problems later in the exam. With a stack of scratch paper, you don’t “lose” your work as you work through the exam.

But, after a scheduling snafu with my local test site, I switched to ProctorU and never went back to my local site. ProctorU was half the cost of the test center and way more flexible with the scheduling options (my test center was only open a few days a week and after they lost my reservation and had no proctor present on the last day of the exam window, I was done with them).

As a whole, I would describe the exams in this program as tough but fair. There are a few exceptions, of course – CS290’s final stands out as being particularly bizarre and nonsensical, but it made up for it by being worth just a small portion of the final grade. Most classes seemed to derive around 20-50% of the final grade from tests alone.

Course content and materials

Unfortunately, as a whole, the course lectures are not great. There are some exceptions (CS492 had amazing lectures), but in general, you can find better instruction on virtually every topic covered by this degree program on YouTube, and you should. There are tons of talented people out there who can teach you how to do a summation or how to step through recursion better than the OSU course materials.

Courses get refreshed every 3 years on a rolling basis (so not all at the same time), and you’ll see people in the Slack channels and the subreddit talking about upcoming refreshes and retooling their schedule to get in either before or after a refresh. In my experience, the refreshes tend to be a good thing – you want to get in after a refresh, rather than before.

The most notable refresh that occurred while I was in the program was the switch from C++ to Python in CS161 and CS162 (with the change propagating up to the higher level classes after I graduated). There was also an elective that got split into two separate courses (Mobile & Cloud became Mobile and Cloud). Also, CS372 became an elective, and new electives were added.

I think these are good changes – they are trying to keep the courses relevant to the industry as a whole and useful to students. When I was in it, CS162 was like being punched in the face every week, but in the three quarters since that change occurred I’ve heard much better things about the class.

Feedback and help

You will get little to no feedback on the code you turn in. I never got any kind of “Hey, you know what might make this code read better…” input on any of the code I wrote for this program. Do not enroll in this program hoping to get 1:1 feedback on your code, because it will not happen. (I did get quite a bit of that kind of help at my bootcamp, though.) This was a disappointment for me in the program. I was accustomed to code reviews on everything I wrote at work so just turning in whatever I wanted and never hearing a word about whether the code style or approach was any good was a weird feeling.

Office hours – most courses had a scheduled set of times each week where you could drop into the Slack chat or a meeting room and converse with one or more TAs about the coursework. I rarely attended these – they were almost always at some impossible time (either they overlapped my work hours or they were right in the middle of the dinner hour) or way too late in the week (I was not going to “save” my problems for a Friday TA chat when the thing is due Sunday).

There’s a Slack channel for every class but the usefulness of each one varied widely. Some were great, with active discussion and helpful links and tips being shared. Others were completely dead.

As I was finishing up at OSU they were moving to a system of having official Slack channels for each class but having a teacher and/or TA in the room seemed to kill any interesting discussion beyond simple Q&A about the assignments.

Other student projects on GitHub/blogs – these were a goldmine of help. Usually the assignment had changed in some way since someone posted their code five years back, but having something similar to analyze was extremely valuable to me. Some OSU assignments are identical to assignments given by other universities, too, so if you find yourself stuck on an assignment just searching for the premise of the assignment might uncover something helpful.

Group work

There is a lot of group work in this degree program and for the most part it sucks.

The group work in this program is at its best when it’s things like discussions on Canvas or Piazza, and it’s at its worst when you’re a team of 3+ and one (or more) of your team members isn’t doing anything at all.

The problem with group work in an academic setting is there’s no recourse for problem teammates. In a professional environment, the team usually has avenues for dealing with a non-performing or always-absent teammate. Generally, managers don’t let someone do nothing and collect a paycheck. In a classroom setting, though, these non-performers are your problem.

I cannot sugarcoat it: many group projects in this program will feature one or more students who just don’t give a shit. I had group members who promised to do work and then just never did it, group members who turned in garbage, group members who skipped meetings and acted like it was no big deal if they turned their part in the same day it was due while others in the group were unable to work until that part was done. I had one group member drop a mess into the codebase and then go out to dinner for two hours just hours before it was due.

The TAs and teachers don’t want to hear about your team’s turd, so it is best to make peace with it and come up with contingency plans for your group’s non-performers. Try to arrange the workload to minimize dependencies – ie: don’t make it so you can’t start your part until someone else has finished theirs, because that person might wait until the 11th hour to do the part you’re waiting on. I’ve talked with enough other students to know that my experience was not unusual. Expect some dead weight on at least a few of your group projects. The group work is one of the worst parts of the OSU program.

Why I enrolled in OSU’s CS program even though I’m a web dev bootcamp grad who already works in software

My first degree is in fine art and my first career was in designing video games. The industry shift to “free to play” style games left me unhappy with my role. I’d always liked making websites, so in 2014 I quit my video game designer job and completed an 8-week web development bootcamp with Code Fellows in Seattle, WA.

My first engineer role was at Expedia, where I worked on a web app that allowed Expedia’s suppliers (people selling tours and activities) to list their products on the flagship website. This was great – I loved the bootcamp and I loved my job at Expedia, but I felt like my long-term advancement might be held back by the lack of a degree. (Some people even made comments to me to that effect, too.)

With decades of career still ahead of me, I decided to invest in a degree to support it.

I was impressed at how many of the topics I first encountered in my bootcamp resurfaced while working on this degree. Recursion, picking the right data structure for the task, interfacing with an API, CRUD operations, writing tests, and performance considerations were all covered in the bootcamp. Doing this degree made me feel even better about how good my bootcamp was! (Thanks, Code Fellows! You guys are legit!)

To me, this CS degree symbolizes my commitment to my new career and dedication to learning. I was already tooling around with side projects all the time, why not focus them into something tangible?

People argue that you can learn all of this stuff online for free, and that is true – I relied heavily on free online resources for every class in this degree – but the program exposed me to (and pushed me through) to things I’m not even sure I would have found on my own. For example, I don’t think I would have built a shell in C or worked through recursive algorithms on my own. I definitely would not have studied discrete math on my own. And I probably would’ve given up on some of the harder things if it weren’t for needing to pass a class motivating me to work through it.

People say you don’t need a degree once you’re already working, but I was called “just a boot-camper” or “just a front-end dev” enough times to convince me otherwise.

With the degree, now I feel like I can do anything!

Job prospects

I was going to fill out this section with a brief discussion of my post-degree job search, but due to COVID-19 I’m in a holding pattern as I wait for my children’s daycare to reopen and for it to be safe to venture into the outside world again. Many companies seem to be on hiring freeze, too.

I’ll write something useful here when I have something to report.

In conclusion

To some extent, it’s hard to say if the degree is worth it when I’m only a month post-graduation and have barely begun my job search (in the midst of COVID-19, no less).

But I can say this: it was a good 4 years and I’m proud of the work I did.

The degree was no replacement for on-the-job training: the degree didn’t touch 90% of the technologies, techniques, workflows, or complexities of the codebase that I encountered in my professional job. The bootcamp I did in 2014 handled those areas better.

Here’s a diagram that attempts to illustrate how much “overlap” there was in topics and learning between my bootcamp, the OSU degree, and the web developer job I had for the first three years after I finished the bootcamp:

This diagram needs a big fourth circle labeled “tinkering around with stuff on my own”.

Just going by what my other CS-degree having friends have told me about my coursework and projects vs. theirs, the OSU program seems to be roughly on par with what other state schools are offering for on-campus CS. In general, the OSU program seems to be more modern than what some of my friends did for their degrees (circa 2005-2015), though less math-heavy.

Overall, the degree gave me what I wanted: the peace of mind that comes from having put in the hours and the work to earn the same degree so many of my colleagues have. I think the degree will open doors down the road, especially if I ever want to do something besides front-end web dev (which I’m actually very happy in). Hopefully, the degree communicates that I am serious about my career change and dedication to CS!

I’m glad I did it.

OSU eCampus CS325 Analysis of Algorithms review & recap

This post is part of an ongoing series recapping my experience in Oregon State University’s eCampus (online) post-baccalaureate Computer Science degree program. You can learn more about the program here.

Six-word summary: brutally difficult, but it’s over now!

CS325 – it me

In CS325 you’ll study recurrences, asymptotic bounds, probably every major sorting algorithm plus some silly ones, dynamic programming, graph traversal, recursion, linear programs, and more.

CS325 Review

Well, the rumors are true – this class is hard. I’d place it in a tie with CS162 for overall difficulty. But where CS162 tries to kill you with a brutal workload, CS325 tries to kills you with instructional materials that don’t adequately prepare you for the homework or the exams.

The lectures are not sufficient preparation for the homework – you’ll rely on YouTube and Stack Overflow to get through each homework question. The weekly homework assignments are time-consuming and the documents you prepare are long. Mine were anywhere from 5-15 pages of graphs, pseudocode, and written explanations for my work.

If you can take CS325 by itself, you should.

There was a noticeable (and distressing) disconnect between what was on the homework and what was on the exams. I scored 100% on the homework assignments, but failed the midterm. It’s like the homework and exams were from different classes!

A week or so after the midterm was graded it was opened up so students could see which questions they got wrong and dispute wrong answers, if they could prove they had it right. I thought for sure I’d prove the TAs wrong on at least one or two of mine, so I reworked all of my incorrect answers – and reworked and reworked them – until I eventually figured out what subtle thing I missed while taking the test.

I definitely struggled in this class, and for the first time I wondered if I even belonged in this CS program.

Class structure

  • 10 weeks
  • 7 assignments total
  • Group work: weekly graded discussions on Canvas, a 3-person group project the last two weeks of the quarter
  • Proctored midterm (20% of final grade), proctored final (20% of final grade)
  • No homework assignment the week leading into the midterm
  • No homework assignment once the group project at the end begins
  • You can bring a 8.5″ x 11″ sheet of typed notes (size 6 font!) into the midterm and the final with you

Tips for CS325

Take every extra credit opportunity (they’re rarer than you think). There was an extra credit opportunity on the first homework, but there wasn’t another opportunity until the last homework!

Comment early, often, and be helpful in the Canvas discussions. There’s an opportunity for 1 point of extra credit in each of these weekly discussions. I was able to earn it most weeks by doing all of the following:

  • As soon as the discussion thread was available, I “structured” the discussion by creating a series of replies, one for each homework question. In each reply, I posted the contents of the homework question for easy reference. This gave each homework question its own thread for my group mates to use.
  • When I figured something out on the homework, I posted pseudocode or a “how I approached this problem” guide to the Canvas discussion to help others. I spent easily 1-4 hours on creating this type of “tutorial”, every single week.
  • I started the homework right away. On Sunday I did the lectures, on Monday I did question 1, Tuesday I did question 2, etc. By midweek, I had half the homework done and was able to assist with answering questions from group members just starting theirs.

This was a ton of extra work. I see why people blew off the Canvas discussions. But the discussions did two key things for me:

  1. It helped my understanding of the various topics to revisit them and “teach” them to others
  2. The extra credit helped me squeak by with a 92.58% in this class, which got rounded up to a 93% (the cutoff for an A). I needed every. single. point. I could get.

Study recursion – put it on your exam sheet! A lot of the class’s materials (lectures, book reading, and homework) will “gloss over” recursive solutions to problems. They’ll be like, “this is the slow way to do it with recursion, now here’s the better way to do it with <the technique of the week>”.

You might be tricked into thinking the exam will want you to know the fancy technique – you’d be wrong. The midterm will expect you to produce the recursive solutions, which you won’t code for the homework or even look at past the few minutes they get in each lecture. I thought this was unfair of the class, so that’s my tip to future CS325 students: study the recursive solutions. Put them on your “cheat sheet”. Know them inside and out!

The extra credit competition among the final project groups is a poorly-designed zero-sum game that you have almost no chance of winning. Here’s how it works: 60+ groups implement algorithm(s) to solve a given problem in as little time as possible, then post their best running times to a Canvas thread. The assignment won’t tell you what “good” times look like – you’ll figure that out by looking at results that trickle in from the other groups. The winner is whichever group (or groups) has the best performance times in the two different categories.

I think this competition could be made better by awarding extra credit to any (and all) groups that can pass a certain benchmark, since that’s hard enough on its own. My group picked difficult-to-implement but highly performant algorithms and did our work in C++ and we still lost to multiple other groups by a little bit. Unless you’re super dying for that extra credit, I think the winning move here is not to play. Take the time you’d spend optimizing your final project towards an unknown goal and spend it studying for the final instead.

The book sucks. (This is the book.) Okay, maybe the book doesn’t suck, but it doesn’t map nicely to the class material and it won’t walk you through how to solve the kinds of problems you’ll face in the homework. I think the teacher requires this book just for the sake of requiring a book.

You’ll need the power of Google (and YouTube and Stack Overflow) to uncover how-to’s and guides for actually solving problems. I still did the readings every week, just in case something useful turned up, but the book is more like an introduction to the topic, not a guide. I relied almost 100% on external resources to actually learn this class’s material.

There are better videos and walk-throughs for every topic this class covers on YouTube and people’s blogs. Seek them out! There are people who recorded themselves going step by step through real problems pertaining to topics like recurrences and dynamic programming in ways the class-provided lecture videos do not. I owe my A in this class to the generous people of YouTube who took the time to demonstrate these difficult topics.

More than any other class before it, CS325 requires self-teaching and finding help on your own. Whether that experience is worth $1900 is left as an exercise to the reader – there is, of course, the argument that self-teaching is what you’ll do on the job so you might as well get used to it, but there’s also the argument that $1900 ought to buy you at least a little bit of hand-holding.

I’ll be in two classes next quarter: CS271 (Assembly and Architecture) and CS361 (Software Engineering I), so say hi if you’re in either of those with me!

OSU eCampus CS162 Intro to Computer Science II review & recap

This post is part of an ongoing series recapping my experience in Oregon State University’s eCampus (online) post-baccalaureate Computer Science degree program. You can learn more about the program here.

Six-word summary: Brutally paced pointers pointers pointers pointers

The beatings are over I survived CS162! If you were wondering where OSU’s eCampus computer science weeder course is, this is it.

The material is challenging and the workload is punishing. The video lectures are crap, but the book is good. The class isn’t well organized (expect poorly written assignments with unclear requirements). 10 weeks is nowhere near enough.

However: I learned a lot. I got faster than I ever thought possible and worked with topics I thought would have had their own standalone courses.

In this article: topics covered in CS162, survival guide, what I thought of the class.

Note: While I normally love to post code here, I can’t share any of my project code (against student code of conduct) or specific assignment requirements, test questions, etc.

Topics covered in CS162

The class is taught in C++ and teaches (or at least requires you to know):

  • pointers to arrays
  • pointers in arrays
  • pointers to pointers
  • pointers to instances of classes
  • passing pointers to functions
  • linked lists made of pointers
  • abstract class and subclasses
  • virtual functions
  • overloading operators (give == an exciting new meaning!)
  • polymorphism
  • writing functions that do something recursively, like reverse a string, sum numbers in an array, solve a math problem
  • data structures: queue, dequeue, stack, linked lists, circularly linked lists
  • sorting algorithms

    Equipment

CS162 is a programming class. Like CS161, I found my Macbook to be sufficient for this class.

I don’t know why they tell people to get a Windows PC and use Visual Studio. I didn’t need it and you won’t need it – there is no assignment based on Visual Studio knowledge.

In fact, judging just by Piazza posts, a number of students seemed confused by the extra files and the “another thing to learn” factor introduced by Visual Studio.

In case you are curious: I did every assignment in Sublime Text and a Terminal window.

Workload

At any given time expect to be working on a 1-week lab assignment and a 2-week project, and mid-course, a group project on top of the first two. You will also write a multi-page document (PDF) for each project with a test plan (input, expected outcome chart), your designs, ideas you changed along the way, reflections on the assignment. This document always took me at least 3-5 hours to complete to my standards. There’s a quiz every couple weeks (15 minutes, not proctored).

I’m a proactive student who started each week’s material the moment it was released, worked on it daily, and generally finished just moments before a new load of work was dumped onto me.

The first two weeks hit like a ton of bricks: a simple Langton’s Ant simulation by itself would have been a large assignment, but CS162 adds a user-navigable menu, input validation, user-adjustable parameters (dynamically sized board, variable turns to run, etc.), and other features that have to be designed, coded, tested, debugged.

Oh, yeah – it has a visual component, too.

There are also two lab assignments to complete while you work on the Langton’s Ant project.

This pattern continues until the end of the course. The toughest week was the one where I was working on a project, a lab, and a group assignment all at the same time.

CS162 Survival Tactics

It’s easy to find people complaining online about how disorganized and intense this class is but what I really wanted when I was in the thick of it was some help. (The OSU eCampus CS subreddit is a good place to look for advice on CS162, too.)

Here’s what I did (or wish I’d done sooner) that made CS162 more bearable.

Take it by itself (if you can)

I know there are financial aid reasons not to but if you’re normally taking 2 classes a quarter, consider taking CS162 alone (or at least with fewer classes than you normally would). It’s a ton of complex material – assuming you haven’t worked a lot with C++ pointers, memory, arrays, etc. yet – and the assignments are black holes for time.

Diagram things out on paper

I found many of CS162’s assignments too complex to hold entirely in my brain.

For example, here’s a crazy thing we did: create a circularly linked list (in C++), let the user fill it and delete nodes from it. When you exit the program, it has to unload from memory node by node. “Empty nodes” are marked with -1 for their values. This drawing I made helped a ton (actually, this was probably the 5th iteration of this drawing).

And here’s another one, this one showing how the heroes in the polymorphism project either rejoin the tournament queue or get kicked out to each player’s respective loser pile.

PS: Some people got really precious about their diagrams having to be works of art, but you don’t have to for these assignments. Just draw this stuff out, paper/pencil (or a little whiteboard) is sufficient, and plan to trash your first few drawings. If you need some material to bulk out your retrospective writing assignments for each project, photos of the diagrams you make are excellent fodder.

Go straight to Google (and Stack Overflow, and YouTube)

Sure, it sucks to pay $1880 to do so much self-teaching but you’ll get a lot of mileage out of the skill. The recorded lectures are crappy and I felt like they were wasting my time. There are better guides to all of the concepts covered in this class on YouTube.

Buy the book

Here’s the book on Amazon: Starting out with C++ Early Objects

I recommend getting a physical copy so you can have it open next to your computer while you work, and use your monitor(s) for your code and Stack Overflow. It’s the same book you use for CS161 (if you haven’t taken that yet, either), so at least you get two classes out of it. You can also buy the loose leaf edition to save some cash.

After two classes with it I can say it’s a good book. The examples are relevant to the coursework, they’re clear and easy to understand, and there are a good number of examples.

Start every week’s material the day it drops – and don’t count on weekends

Sometimes the new week will be released on a Friday. Sometimes a Saturday. Sometimes a Sunday! And no, the instructor doesn’t move that week’s deadline out just because you lost the weekend due to the materials not being released in a timely manner.

For this reason, I recommend setting up your life (at least for these 10 weeks) to allow for working on this class work during the week (ideally daily). Don’t expect to fit it all into the weekend. Even my light weeks were at least 15 hours spent on the class (usually closer to 25 or 30).

Check Piazza religiously

If they improve anything in CS162, I hope it’s the unclear assignment requirements. They requirements were notoriously bad – assignments are written in a conversational style and it’s hard to know what is really being asked for.

Many students took to Piazza (the class forum) to question (or worse, debate) the requirements until a TA or the instructor herself came along to clarify.

Pretty much every week went like this:

  1. New assignment comes out – oh no, it has unclear requirements
  2. Someone asks for clarification on Piazza
  3. TA makes a call and says do it X way
  4. 2 days later, another student asks the same question
  5. Different TA makes a different call on this new thread and says do it Y way
  6. They have a fight, triangle wins…
  7. You already coded it, so do you redo it to Y or keep it as X or what?

For what it’s worth, every time this happened (and I had already coded it), I kept my code the original way and still got 100% on the assignment.

Test on Flip!

So many things happened in my code in the Flip environment that did not happen on my Macbook. Weird things, too – things that weren’t easy to spot without thorough testing. I made the mistake of not testing on Flip until I thought I was done with the assignment, only to find heaps of bugs that only occurred in that environment.

Only after the class ended did I find out about this awesome way to use Git to deploy to Flip. (I was uploading in Filezilla like a n00b.)

Use Valgrind early and often

It’s a memory management tool that’s already installed on Flip and you won’t be able to find memory leaks without it. If you wait until you are done coding your assignment, it will be harder to find the memory leak. Upload your code and check it with Valgrind every so often and you will save yourself a lot of pain.

The worst weeks were weeks 1, 2, and the final project. 

Okay, they were all brutal. There were many weeks where I thought there was no way I would get everything done and I’m a workaholic. The biggest workloads were the first project (Langton’s Ant) and the final project at the end (make an adventure game).

You do actually have to contribute to the Canvas conversation topics

It’s a misguided requirement because these “conversation” threads quickly turn into 100+ people dumping commentary and links in one place. It’s not a conversation, it’s just a dogpile.

But if you contribute a few posts (I think I made 5 decent, paragraph-sized comments between January and March, evenly spaced throughout the quarter), it’s an easy 20 points that you will (probably) be very happy to have at the end.

Take every quiz twice

(Unless you get a great score the first time around, of course).

You get two attempts for each quiz. A quiz is 20 questions in 15 minutes. (I liked this format). Only the grade from the last attempt is kept. Questions are drawn from a larger pool, so you won’t get exactly the same ones the second time you take it.

My strategy was to use the first attempt to see what’s on the quiz and make my best guesses as to the answers. This gave me a feel for the questions and sometimes revealed tricky ones. I usually got about a 16/20 on my first try but Canvas tells you which ones you got wrong, and what the correct answers were, so this is a chance to see what you missed and study it some more. After a little studying I’d retake it, usually getting 18/20 or 19/20 that second time.

Grading

The final’s worth 15% of your grade, so save some steam for the end. There was a bonus, extra credit lab announced right at the last minute, too, but its points could only be applied to your lab grade.

  • Weekly labs – 30% of your grade
  • Quizzes – 15% of your grade
  • Projects – 30% of your grade
  • Group activities – 10% of your grade
  • Final project – 15% of your grade

Overall impression: OSU CS162

I hated it at times, but it was worth it. I never would have pushed through some of this stuff on my own, without a grade and a degree motivating me. OSU’s online CS is meant for people with a full-time job and the occasional signs of life outside of class but I had to take a couple days off work here and there to accommodate the workload, and I barely saw my family. The most difficult parts of this class – deciphering confusing and unclear requirements – were totally unnecessary. OSU should hire a proofreader and clean up CS162’s assignments. And some weeks the workload was just pure insanity – the week with the group project stands out in particular.

But… it’s over! And I got a 97%, so I’m going to take a much-deserved week to rest up for the next class.

Onwards to CS225!
