-Ok I definitely took this man for granted when I had him as a professor. I had him during my first quarter at UCLA, so I didn't really have any other professors to compare him to and didn't realize how amazing of a professor he is. Take a class with this man if you can! A professor as good as he is in the math department is extremely rare.
-The first midterm was very easy. It was out of 75 and the only objectively "difficult" problem was a 5 point problem which no one really knew how to do.
-The second midterm for me was a different story, but many other people did well even though I did not. I admittedly didn't study that much and got a C, so I consider it my fault.
-After my performance on the second midterm, I grinded really hard for the final and got a 97%. Many people thought the final was very difficult; it definitely wasn't a walk in the park. It was 15 questions. Many of the questions were difficult when I first read them, but after staring at them for a while or working through them, I found my way. Overall in the class, I got an A because you can drop your worse midterm.
-The homework in this class is technically optional but DO IT because there are short quizzes each week during discussion sections, and 99% of the time, the questions are verbatim from the homework.
-A lot of the material in the class centers on topography and the structure of graphs of multivariable functions, and Mike Hill actually specializes in topography, so he knows his stuff and knows how to teach it.

Professor Hill is good at explaining the material, although I do think 32A material is pretty easy regardless. He's a fair professor. I don't believe he curves (simply based on the midterm/final averages), but he doesn't need to. The midterms are fairly easy, and if you can do the practice final, you'll be fine for the final. I recommend this class if you're willing to go to lecture, pay attention, and do the practice tests that he provides. Also, the discussion worksheets are way harder than the final, so if you have no problem doing the discussion worksheets, the final will be a breeze.

Hill was a super engaging and funny lecturer. He is very clear, and he had his office hours on the Hill because he is a Faculty-In-Residence. I blame myself for doing so badly since I couldn't dedicate enough time to the class, but if I had been able to I believe I could have done better, despite not being amazing at math.

His discussion worksheets are pretty difficult but are useful for preparing for the tests. I would also recommend doing many practice problems from the textbook (all the homework assignments, even if they aren't collected).

One of the easiest 32A professors from what I understand, despite a surprisingly hard final. Very organized, clear lectures. HW is not collected, but do them thoroughly because the section quiz questions are taken directly from the assignments. Overall great professor.

Probably the best math professor I've ever had. He was one of the clearest and concisest math professors at UCLA. His office hours were helpful as well. However, one strange thing is that he doesn't assign homework, but rather gives quizzes during discussion, so they are mandatory. I would recommend taking him if you really want to learn the material well.

Hill was a wonderful, passionate lecturer who was clearly very knowledgeable about the material. He gives quizzes during discussion, but they weren't bad. Exams are not easy, but they are doable. He's also very accessible outside of class, in case you have any questions about the material.

Hill was a fantastic professor for Math 32A. Being my first math class at UCLA, I think I took for granted how much he cares about the success of students, their understanding, and their enjoyment. Hill hasn't typically always taught lower div math classes, so if you get the opportunity to take anything in the 31-33 series with him, I would highly highly recommend it.

Here's some things to know/consider:
-(As of 2019) Hill is a faculty in residence. This is super cool because his office hours are hosted on the hill in a large spacious room. Always places to sit and get help. His LA's often will come to and walk around to help with homework/questions. Go to them!!

-Rather than collect homework, Hill has weekly quizzes in discussion which are mandatory, but they are basically identical to homework problems, and you can drop your lowest quizzes. The homework assigned itself is a very reasonable amount, maybe took me about 2hr a week to complete.

-In his class, especially for the 2nd midterm/final, it is critical you understand the conceptual stuff, not just the math. Really understand gradients, partials, directional derivatives, curvature, etc. Final was very reasonable; new problems but nothing foreign or impossible. Watch out for 2nd midterm, I ended up dropping mine.

-Since the exams are all pretty reasonable, the curve is very high - if present at all, so don't rely on it.

-While Hill is a good lecturer, he sometimes can shy away from applications/physics of 32A, which can make concepts harder to understand since without it, it's pretty abstract. Don't be afraid to look stuff up on your own.

-When I took him, there was nothing for his exams in the test bank. That may have changed since, but it did make preparation a little harder, since all we had were practice exams he wrote.
