This class was horrible for me as my first introduction to college-level calculus. Wenhao as a professor is not a bad person by any means, but most of the time in class I felt completely lost as to what he was covering and spent probably 2-3x the amount of time outside of class trying to understand what it was he was *attempting* to teach. I learned pretty early on that he would teach things in a way which made no sense, and people in that class who had taken high school calculus before constantly were telling me of better ways that they had to solve problems. It was extremely frustrating to go to lecture and be taught something in a very convoluted and complicated way, only for Wenhao or someone else at the end to finish with "so all you need actually is this one equation lmao". Much of the class felt like a waste of time, and while I understand the value in deriving equations, I never understood when Wenhao was deriving an equation or when he was actually teaching how to solve a problem. This class was super confusing for me, and while his two midterms were almost identical to the practice he gave out, his final certainly was not--our average was around 77%, whereas for both the midterms the median was in the mid-90s. I'd definitely recommend a different professor if you haven't already learned the material--if you have had previous exposure to it, however, he's probably not your worst choice since you already have an idea of what it is you're supposed to be doing.

Wenhao is a nice guy, kinda awkward. During his lectures, he writes everything he says down, so that’s nice. You should take his class just for the exams. The practices he gives out are the exact same as the actual midterms, he just changes the number, usually to make it easier. The average on the midterms were a 96% and 88% respectively and the final was an 82% (but the median was an 86%). Make sure to redo all three practice exams for the final, but focus the most on the third practice. Homework is really easy too, just like 10 practice problems a week. Discussions and Lectures are not mandatory, so you don’t NEED to go if you read the boo and do the practice tests. My friends took other professors and their exams are A LOT harder to do and they required proofs (I’m looking at you Susice). For reference on how easy exams are, one problem was determining whether two vectors are parallel (you’ll get how easy this is when you take it, you just for two vectors and if it equals zero, they’re perpendicular) and another was just doing the cross product of two vectors. Overall, TAKE WENHAO!

The class itself is pretty easy to pass. The practice exams are almost exactly the same as the actual exams which makes preparing for tests easy. Lectures were often confusing and didn't make much sense, but if you have the textbook you can teach yourself practically everything. Overall, Professor Ou's class is easy to pass aside from the confusing lectures.

Your grade only comes from homework and exams. The homework you can miss two and be fine and honestly it seems like it is barely checked. The exams. THE EXAMS ARE THE PRACTICE EXAMS. I was kinda screwed this quarter because I had back to back lectures who gave exams on the same day. So thankfully all I needed to do was glance at the practice exams and I was ready. If you don't score perfectly however, it will hurt. The median grade for our first midterm was a 99%. Also for a class that is mainly the practice exams, his practice exams are riddled with errors. Best advice I can give is to go to discussion have have the TA just go over the entire exam.

Straightforward class with a straightforward teacher.

I went to the lectures sometimes, given that I study the textbook by myself.
The first half is very easy. The second part it gets hard to comprehend. I would suggest reading the textbook and go to class for comprehension and his equations(some not found in textbook)
Study his practice midterms and finals. Because that’s all it’s going to appear on your real exams

Professor Ou deserves so much more than the ratings on Bruinwalk. First off, Ou’s accent is not even that bad. Yes, it’s very noticeable, but you could totally understand him if you were even trying a little bit. It frustrated me that so many people kept laughing at him during the first couple of lectures, and you could tell that he noticed them. LEAVE HIM ALONE. Sure, he would spell words wrong here and there, but you knew what terms he meant. There was no need to publicly humiliate him like that. My friend took Brizolis, who is known to teach well and have no accent, but she ended up having to drop that class and retake it because of the overly difficult tests. On the other hand, Ou is such a fair professor and although there is the “grade distribution,” he doesn’t really go by it because he believes that if you deserve an A, you get an A. The few times I missed lecture and copied notes from a peer, the notes were so clear because Ou introduces methods in steps, and you can memorize them.

None of the 31A professors are great, but Ou is fair at least and teaches pretty well. He was confusing sometimes, but for the majority of the course, he explained concepts clearly. When I attended his office hours, he gave me his full attention and explained things in detail. In addition, the TAs were super helpful, but barely anyone attended their office hours. I would be the only person there for some weeks. The practice midterms are very similar to the real midterm. If I messed up on a test, I felt it was more frustration within myself rather than towards the course. I constantly checked in with Ou about assignments and discussed how I wanted an A in the class, and this helped him know me as a student. Overall, I feel very comfortable about my choice of taking Math 31A with Ou and believe he was the best choice compared to the other professors at the time. Math is one of my weaker subjects, and I worked really hard for my A-. If you don’t understand something, email Ou and your TAs or attend office hours. They’re happy to help you.

Selling loose leaf textbook for his 31A class, it's the same one you use in 31B also. somewhat used for $50 email 31A*************

The professor taught the material pretty well and gave helpful practice tests which were very similar to the real ones.

Let me preface this review by saying that I got an A+, so none of this is coming from a place of resentment about my grade. Wenhao Ou is a TERRIBLE professor. First off, his English is awful. He has a thick accent and talks extremely quietly and never faces the class, thus if you are not on the edge of your seat in the front row, you will not hear a word he says. Secondly, this guy is completely unorganized! He often arrives late and sometimes does not know how to prove the "simple" results that he offers as examples. Thirdly, Ou is an unfair grader. On a midterm, I wrote "for all it is not" instead of "there does not exist" in one line of an 8 line proof and he said that it was "unreadable." What a joke! Anybody who has taken Phil31 or any proof based math class can tell you that the negation of the for all quantifier applied to ~x is the same as negating the existential quantifier. As far as the material, I would have learned algebra better from an uneducated pile of dog shit. By the 8th lecture, our class of 35 was down to 8 attendees, so that proves just how helpful this bozo is. If you are still reading, DO NOT TAKE Math 110A with Wenhao Ou unless you have to or you already know some algebra. If you can teach yourself the material, the tests are doable, but if you rely on a helpful professor, then this class is not for you.

Professor Ou is the worst teacher I've ever had. I took Math 31A with him and he is unintelligible. Honestly his English is nowhere near proficient and more so he is standoffish in his OWN office hours. He taught concepts in the most confusing way possible. Avoid at all costs.
