Introduction to Discrete Structures
Well Bateman was actually a pretty good teacher. The main problem with this course is that if you miss a class or dont understand something the book really does not help that much at all. I had to ask the T.A. a lot for help. Also the homeworks are pretty hard but short, I needed to visit the T.A. a lot about those. The tests are actually really hard, except wasn't too bad but the average on all of them was around 50 so he curves them nicely. I would focus on getting as many questions fully right as possible instead of bullshitting as many answers as possible. So quality over volume kind of deal, not too much partial credit.
I took Math 61 with Professor Butler last quarter (Fall 08)--and I have to say, it was one of the best math classes I have ever taken at UCLA. Professor Butler is very organized in lectures, clearly knows the topic really well, and is really funny in lectures. Sure, sometimes the lectures could get a bit dry, but hey, it's math. If Professor Butler is teaching any of your required courses, I strongly recommend him as your top choice.
Winter 2019 - Uh this professor doesn't know jack and can only recite definitions from the textbook, but expects us to do proofs... so tldr don't take him unless you understand the material already because the textbook isn't clear and the professor doesn't teach. Also, if your TA is Ben, be ready to ask a question and then have take an hour to work it out with you by asking YOU how to do each step, which you most likely won't know how to do because you're asking the TA the question.... TLDR: don't take this prof and go to another TA other than ben :)
Winter 2022 - I liked this class a lot - I thought the professor was a good lecturer, and the lectures themselves are very clear and well-organized (though unfortunately not recorded). The homework is graded on correctness but generally weren't too difficult, aside from a few tricky problems. We had two midterms and a final - in terms of exam format, the questions were all fairly straightforward and similar to those in homework/lecture, with the exception of each exam having a question subpart (usually worth ~5%) that was noticeably harder than the others. I didn't attend many office hours personally, but the professor would almost always be going over homework problems.
