Tony is a great professor, and super nice guy. His slides are also pretty quirky which is entertaining. If you sit in the front of the lecture hall and pay attention to lectures you will learn a lot and studying for exams will be a lot easier. Going to office hours was super helpful for me since he will sometimes give direct hints about how to solve the labs. They gave the option to attend discussion and get credit for effort on the weekly worksheets or not attend discussion and get credit for correctness. I would recommend going to discussion since the TA's are very helpful and you don't have to spend your Fridays hashing out the worksheet you forgot to do.
This was my hard class this quarter and I literally spent 3 entire days studying for the final exam, but it was all worth it. Tony gives past exams as practice so definitely do those when studying.

I don't get why people like this professor so much. Lectures were not clear, at the end of the quarter, the lecture room was almost empty. The textbook is great!

Not a difficult class to get a good grade though. Good curve, but you probably won't need it anyway, as the subject is not difficult

Pretty good class.
Midterm is mostly assembly based problems (tracing through everything to figure out what the program outputs). Average is roughly 60% for that midterm even after curve, but I'm pretty sure the professor curves the scores even more when doing final grades. Final is more oriented towards things like cache and memory mapping, and the average on that one was around 75-80% after curve. Projects are interesting (they got rid of malloc lab), and shouldn't take too much time compared to CS32 projects.

The lectures are fun and interesting too.

tony is great but the main thing this class taught me was to never touch gem5 ever again

I feel out of all the professors who teach CS33, Tony is probably the best one imo. While his final and midterms can be tough, his is very fair in his grade distributions, with around 50% of the class getting an A- or above. Tony's lectures were good but I felt in person he would move too fast for me to keep up, so I typically just watched the recordings. The labs were pretty easy compared to CS32 and CS31 labs in my opinion, but they are definitely more conceptual and require an in-depth understanding of the material. The most "annoying" part of this class is that discussions are "mandatory" -- are 10% of your grade but skipping them increases weightage of final from 40% to 50% -- but I actually found the worksheets, my TA, and LA very very helpful. Regarding the exams, they were very conceptual and a lot of questions were all or nothing, but again his curves are very generous. All in all, hard but fair course. ty tony :))

Nowatzki is an amazing professor (and an even better Overwatch player). He is super kind and made this class much more bearable. The actual content of this class is wildly different from CS31 and 32, so don't come into 33 expecting to use Xcode or anything like that. You will literally only write like 30 lines of code over the entire course. Everything is very conceptual and you actually need to understand the concepts to apply them. Nowatzki is also very VERY generous with grading and curves the class and tests a ridiculous amount. It is nearly impossible to fail this class and considering the material, that is a miracle. TLDR: take Nowatzki because he is the best 33 professor to ever exist. Also shoutout Aditya! (the best TA ever!)

Tony is just amazing. I'm hoping he teaches M151B one day.

Tony is undoubtedly my favorite professor at UCLA. He is very passionate about the material and makes lectures very interesting and engaging. Projects take a lot less time than CS32, although the material is a bit harder conceptually.
His exams have low averages, although don’t be worried, I got C’s on both exams still very comfortably got an A in the class.
There is a lot of extra credit on exams and projects, and office hours/ discussions are super helpful.

I really liked Professor Nowatzki! He's a fair professor and his lectures are engaging, even if the subject matter can be complicated. The projects don't take too much time and can actually be really fun with the scoreboards and everything. The class is very heavy on material, however, so make sure to stay on top of your work!
