32B is probably the hardest class I've taken at UCLA so far, but Willis makes it as easy as can be. His lectures are engaging and easy to follow, and his explanations are amazing. The midterms are pretty similar in difficulty and kind to the homework. Plus, we had Bruincast. Take him if you can!

Total baller, taught concepts that seemed complicated in the book with real clarity, and was always willing to answer questions. Ran lecture online well, still felt that I was learning over zoom clearly

BEST PROFESSOR EVER.
Funny, engaging, caring.
Maybe I will major in math because of this guy.
The exams are not hard which means being a bit careless will ruin your grade...

Best math professor I've had in the entire 30 series. Willis is so clear in what he wants to teach you and tries to find the best way for his students to absorb the material. His notes are concise but full of information. He lectures very well and it doesn't take too much effort to keep up during class because he is so well-paced it barely feels like a quarter-system class. He always took time to answer any questions in the chat, even if it meant falling slightly behind in lecture. I feel like the material in 33B is easy to compute but difficult to truly understand in theory, but I was really able to grasp what was happening intuitively through the way Willis explains. Tests were very fair in material and length and did not take the whole 24 hours. Take Willis, even if you don't like math! He is such a g.

Willis is an amazing prof. If you have the chance to take a class with him, do it. Homework is 30% of your grade and it is very easy to get all the points here. Half of it is Sapling problems (infinite tries to get 100%) and the other half is written problems. If you have any issues with the written problems, he will go over them in office hours which was super helpful. His lectures were engaging and he made them fun. He was also very good about watching the chat to answer questions as he went. Discussion sections are entirely optional, but I found it helpful to attend. Two midterms, each of which are 20% of your grade (covering the first and second third of the material). The final is 30% of your grade and cumulative. He provided an old exam for all of them for us to use as a study guide. Overall, his class was fun and he made it very easy to succeed!

best math teacher hands down. ive always struggled in math (flunked calc in hs) but wilis explains concepts/problems clearly.

HW was reasonable. It was around 20-30 online Sapling questions and 3-6 written problems from the textbook. He also drops the lowest score for online HW and written HW. If youre stuck on a problem, he’ll do the problem during OH.

To do well, you should probably try to fully understand the practice tests. Willis’ tests are fair, I would say a little harder than the practice tests. I had 24 hrs to do it + open note so it was doable.

For someone who is good at math, this class should be easy. If you’re not so good at math, like me, try to understand the HW questions fully and go over the concepts he gives in lecture tbh.

Willis says he curves up if the class averages are a little low. Honestly, don’t put all hope on the curve tho. I got a C- , B+, and A- on Midterm 1, 2 and the final if that helps.

Willis’ only flaw is that he doesn’t like pizza.

I thought the course material was fairly straightforward, and Prof. Willis certainly helps make it even more so. He's a clear lecturer and he's always willing to take questions during lecture, help out during office hours, and take suggestions from students about the course structure, which was key since Spring 2020 was remote/online.

The overall grade is: weekly homework (20%), two midterms (20% each), and the final (40%). Exams were fair, possibly even more so than the homework assignments, each of which always seemed to have one really tough problem.

In general, I'd definitely recommend taking 120A with Willis.

One of the best professors I will probably ever have. Willis is super articulate and is a very visual teacher (something that's important for this class). He's also super funny and interesting in office hours. I'm so glad I had him as a math teacher, would 100% recommend to anyone.

TAKEN DURING COVID
Willis is really good at what he does. Thorough, intelligent, and engaging with the class. The workload was alright, a few times it seemed a bit much but that was probably because of zoom tbh, I have no motivation so that probably contributes to not wanting to do the work. Aside from that Willis was pretty nice and helpful, office hours he was really chill. The discussion section seemed like a waste but that could be just me. People said his tests are hard, not really to be honest. The practice midterms were practically the same as the actual midterms, so as long as you can solve those you can pass. Good first professor and class.

I really enjoyed taking this class with Dr. Willis. I had to switch to 32A a little late in the quarter and I was worried about getting a spot since I was behind some people on the waitlist. Dr. Willis cared about my situation and assured me I would be enrolled off the waitlist. His tests does have some proof questions but these proofs are based closely on topics discussed in the textbook and class. I highly recommend taking this class with Dr. Willis.
