This was my first time taking a CS course and the way the material was broken down and presented was manageable even for a complete beginner like me. The course mark was based on 7 projects, 1 midterm, and 1 final. The projects were reasonable (#3 took up more time than the others tho) but make sure you don't start them last minute and take advantage of office hours if you get stuck. The midterm/final were very straight forward-- make sure you understand the projects because the tests were heavily based on concepts seen in the projects. Overall I enjoyed the class and bonus points for the professor's dog who would often show up on camera.

Stahl is a great professor, although I did take computer science in high school, so I had an advantage. He tells you all you really need to know for the projects, although for one of the it was really unclear, but he has a forum where people can ask and answer questions. He provides a lot of tests for your programs to make sure you are heading in the right direction, and the only tougher part about this class is the final because the harder material is pushed towards the end and there were some oddly specific questions that I could not find the answer to anywhere.

Howard did an amazing job of teaching this course in such a way that even though I had no coding experience (it took me a couple of days to realize int meant integer haha) it was by no means a hard or difficult class. The workload could at times be excessive, but that is just the nature of coding and the time you have to put into actually typing code, and even testing it. It really helped me initially to attend OH and ask clarifying questions early on, but after week 4 I had a strong enough understanding of the course and its material to really breeze through the class. Tests are easy, projects take time, lecture could at times be confusing but was overall very clear. And pixie is a big plus :)

He has a habit of going on tangents and making the material more confusing than it needs to be. I recommend looking up topics if you don't understand them after lecture. Nevertheless, Pixie is a cute dog. Would take again.

I'm gonna list the cons of the class only here since others mentioned accurate stuff. If you have no experience in coding and are bad at test-taking, do NOT take this class. The one midterm provided is worth 25% and final is 35%. Moreover, he would never accept a regrade in a test.

Howard is super sweet. He's not the easiest to pay attention for 2 hours straight (though he does end lecture earlier quite often considering he doesn't give a break in the middle like other 2 hour classes do) so I honestly found myself slacking and multi-tasking during class. However, he isn't a bad lecturer by any means and comes up with pretty good explanations for topics. I didn't know programming coming in but I think I was onboarded pretty well. I did find myself having to use outside resources alongside since he didn't explain everything the best. The projects are the standard CS31 ones. Project 3 is by far the most time-consuming one and is very difficult if you have not ever used recursion or thought in coding logic--however please don't feel intimidated by how 99% of the class seems to have been coding since they were born. Go to office hours, watch YouTube videos, and don't give up! Exams definitely tested on a lot of tiny quirks on C++ but overall was pretty doable for somebody who didn't pay too much attention in class.

If you come in with coding knowledge, this class will be easy for you and lectures are going to be very boring. If you don't know how to code, Howard will walk you through everything. If you've never coded in C before, pay attention to his lectures on pointers and make sure you take good notes. The 2-hour lectures could definitely be shorter. He occasionally ends lectures early though if he gets through all the material he had planned for the day. When working on the projects, make sure to pay attention to the specs and any extra spec information he gives in class. Like any class, make sure to start projects early and break it up into chunks.

Howard is super good

Stahl is a lovely guy but my god were lectures tough to sit through. I ended up stopping going halfway through and watching the Bruincast at 2x speed because he speaks so so slow. Projects were ok but usually a little long and as a complete novice when it comes to Computer Science, I struggled a little but office hours were super helpful. Midterm was easy with a cheat sheet and I didn't take the final because due to Coronavirus, he allowed us the option to opt out. He is super helpful and does care about his students a lot, especially if there's a grading mistake or if you ask for an extension.
He probably one of the better professors for this class and is a really nice guy so I would suggest taking CS31 with him. Plus if you have any C++ experience you'll find this class a breeze.

Professor Stahl is a great person but it is almost impossible to sit through his lectures. If it is bruincasted which it most likely is, watch those on 2x speed. His lectures go over material and things needed for the project; nothing much else. Discussion helped me the most if you get a great TA (Angelina Poole is the best!). Projects are decent; one of mine I mistyped something when uploading a project producing a compile error and getting a 2/100. But I emailed him and he fixed the error and rerun it for me giving me a 100. He cares for his students so much, and he is super lenient with tardiness. However, he does not prepare you well for cs32... The transition from 31 to 32 (which I had Smallberg) was quite hard for me. Overall, Stahl puts his students first, and is likable; if you know the material, then projects should come by relatively easy.
