Spring 2021 - Regan: cool funny guy tests: crazy hard homework: ALOT hbar: stupid human constant don: enlightened the curve: GNARLY fr fr tho, prof is super dope, funny and knowledgeable. He teaches QM with his own twist, which was weird at first but later it kind of grows on you.

Spring 2024 - Yaroslav is a knowledgeable professor and I learned a lot of important physics in the class. He is, however, a lackluster lecturer, but if you read the textbook, you'll be able to understand whats going on 99% of the time. His tests are very reasonable and he pulls a lot from the textbooks and homework. Sometimes there is time pressure during the tests. Although the averages were in the 50s and 60s, I think it's due to a lack of preparation. The homework was 4-5 problems from Griffiths and the pace was on the slower side. The lectures were mostly beneficial for a more philosophical understanding of quantum mechanics and his notation was at times difficult to follow. I would highly recommend this class though and Yaroslav is a funny guy.

This is quite possibly the worst professor at UCLA. To start, the book he chose to teach the course was full of errors, many of which he noted himself. His lectures were just filled with formulas and derivations which he failed to explain, and his notation was inconsistent, making it difficult to follow. He was unhelpful during office hours and sometimes could not even answer the questions he assigned. His TA was extremely lazy and was never available. Don't take a class with Williams, it will ruin your quarter.
