(I took 32A, not 32AH) Williams is honestly a pretty average (in a good way) guy. I have no complaints with him; he has no collected homework, weekly quizzes straight from the book (usually easy), and very fair exams for which he gives you lots of practice. He's not the absolute best math professor around, but I'd take him over Chayes (the other usual choice for 32A) any day. In shot: Not bad; wouldn't mind taking him again.
Professor Williams was above average. He is clear and is able to convey the concepts well. His voice is pretty bland, and his jokes take a few seconds to understand. I had Mess for 32A the quarter before, and Williams was a huge improvement. His exams are fair, though there was a tricky question on the first midterm. He drops the lowest two quizzes and the lower of two midterms. I think he curves a little, since my calculations told me I'd get a B+, and I ended up with an A- (not that I'm complaining), but that may be because the final had a pretty low average.
Great professor. Really loves what he does and simplifies things in a way that makes the material really easy to understand. He understands what its like to be a student to the point that he drops a midterm if you didn't do well cause everyone has crappy midterm days. He's also really funny. I would definitely say he's the best professor I've had since I've been here. He gives weekly quizzes in section based off the homework, which means if you already understand the material then you don't really need to do the homework, and he also dropped the two lowest quizzes.
Williams is pretty good. He speaks in a monotone, so if it's an early morning class, you'll have to get some coffee. I will say that MATH61 is brutal over the summer session, though. There's a tremendous amount of information crammed into 6 weeks and little time with which to practice exercises in between lectures. Like I said, WIlliams is a good guy, but summer session is not the optimum time to take this class, IMO.
Winter 2021 - COVID REVIEW Hands down one of the worst professors I have had here at UCLA. He was completely unresponsive to emails and questions practically the whole quarter, and your grade is based on 5 tests that he makes. Questions would be unclear on what they wanted you to do to the point where no one was certain what he was asking for, and his lack of response overall made this a terrible class. Really hoping the Accounting department steps in to address this, but I really don't recommend taking any classes with him at least during COVID until these issues are addressed (because he seems very experienced and knowledgeable).
He's a really solid professor. He has a very dry voice and sense of humor and his side comments can be hilarious. He presents the material well and is easy to understand, and is good at explaining problems in a step by step manner. Definitely one of the best math professors I've had at UCLA. His class is pretty standard with 2 midterms and a final, he assigns but doesn't collect homework, and there are once a week quizzes that take two questions straight from the homework (so plan on attending discussion).
