Tony is the GOAT and I mean it. Best class I have taken at UCLA. He is an extremely good lecturer and he will explain things in a way that makes sense and will spend time helping students understand in class, He has amazing slides as well that are super useful. Personally, I did not read the textbook as I feel everything he teaches in class and in discussion is sufficient (except perhaps you should know the basics of C programming going in - malloc, pointers, strings, etc: be able to print "Hello world!" with a dynamically allocated (malloc) string and you are good). He is for sure the BEST CS33 professor you could ask for.

This class is one of the hardest classes I have taken at UCLA. The professor is a good teacher, however, he covers his slides so fast that I couldn't take notes during lecture or I would fall behind. Instead I used the recordings which were much more helpful to me since I could rewind if I did not understand something and also double speed the lectures. CS33 exams require knowing all exceptions, having a detailed understanding of all concepts and also having a higher level understanding of how these concepts work when combined together. Tony can convey these ideas in his lectures, however, I felt like I was still missing a lot of concepts so I always read the textbook chapters he assigned before the midterm and final. I also reviewed the exam slides because exams are usually based on what are covered on the slides. But if it were not for the textbook I would be toast on both the exams. The labs are challenging but doable. After bomb lab, the labs get easier.

Tony is a legend. TA Salekh is even more of a goat and is super helpful and carried me through class. Though lectures were a bit dry, I learned a lot from this class and I would definitely take again. First lab is kind of hard but once you pass that, it is okay. Exams are pretty hard but curves are generous. As long as you study everything, you should be fine.

Tony is forever the goat for this class. Tony makes this seemingly daunting class extremely simple and easy to follow. Of course, you will be lost during lectures (because the material is so difficult), but the logistics of this class are fantastic. Call me crazy, but I might take cs m151b in the future only because Tony made this class kinda lit. Still hard af tho.

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!

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 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.

This class was pretty difficult and a lot different from CS 31, and CS 32, focusing more on low-level computer hardware and programming concepts. There are five labs in total, which are pretty reasonable and help solidify class topics. The malloc lab is really difficult, and I would definitely recommend starting it as early as possible. The textbook isn't necessary, as Professor Nowatzki is a great lecturer and has informative slides.

I want to become Tony when I grow up

This class is very difficult and Professor Tony speaks really fast. Malloc Lab is hard. Final exam is way more difficult than the midterm.
