Such a wholesome guy. Take him if you can.

Can't recommend this professor enough. Wenhao's exams were almost identical to the practice exams he gave out, with just the values changed.
He is a little sparse on communication (he doesn't use CCLE) so make sure to attend lecture or make a friend that attends lecture to stay up to date. Or don't, you'd probably be fine that way, too.

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

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.

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.

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!

His accent made learning a little difficult, but the topics covered in class were not too difficult. The tests were almost exact copies of the practice tests he gives out. Lectures are pretty useless, and you could probably not go to class and still get an A. The final is a lot more difficult than the midterms.

I would definitely recommend taking this class. I ran into a few problems because some of the material is only covered in lecture and if you miss it, it can be hard to find it in the book. Also, homework problems were never graded nor were solutions posted, so I highly recommend getting a group together to work on homework solutions and practice tests together. My TA was not very helpful because he was not specific to Ou's class and didn't seem to know very much about what we were covering. I think he gave out a lot of A's this quarter, so that was nice.

Professor Ou is a very fair professor. He writes everything on the board when he lectures so it is always clear what he is saying. The workload is fairly light, and the practice tests are exactly like the actual tests. A bit of an awkward man, but overall a great professor!

Professor Ou is a good professor to have for 32A! His lectures, albeit a bit boring, stick to the material being tested on/what's on the homework, and his accent does not really inhibit his students from learning. It's not that strong, and he writes everything he's saying on the board anyways. He does do proofs for certain theorems/formulas that aren't necessary for the test, but they're interesting to learn about if you find math interesting. If you don't, just copy them down and never look at them again, because they're not necessary. He doesn't allow cheat sheets on exams, but his midterms are exactly like the practice midterms, so studying those are all you need to do for the two midterms. The final is more difficult than the midterms, but the concepts are all familiar. To study for the final, I suggest going over the past two practice midterms and doing the practice test for the last third of the material from after the second midterm. I never went to office hours, but I heard he's helpful. His homework load is not heavy at all; it's one assignment per week from the textbook, and there's always less than 20 questions on each one. Discussion sections aren't mandatory, and he doesn't seem to care about tardiness to lectures. Overall, a good professor for 32A! I've heard other professors are a lot harder.
