Taking 102A and 102B with Wu was the worst decision I made in my three years at UCLA.

Bro just fired him

I'm a poli sci major that hates math, but Wu made this fairly painless. He's an incredibly nice, personable, and helpful professor that clearly cares about students succeeding. The content isn't that interesting but Wu teaches in a very clear manner that made it fairly easy. It is easy to get behind, however, so I'd recommend staying on top of lectures and actually reading the textbook (I think I'd space out on a lot of the lectures if I didn't have the textbook's background knowledge).
The lab portion of Stats 10 is totally ridiculous, but most TA's walk you through it step by step so it's fine.
Wu writes pretty hard exams, as well. The midterm was easy but he used relatively confusing language that lead to the mean score in the class being 73. The final was also hard, with a mean score of a 72... so take studying for the tests seriously. In my class he curved pretty generously (dropped a few low scores and rounded some things up, I believe), but I'm not sure if this is the norm.
If you have to take stats 10, Professor Wu is a good person to take it with!

I took 102b with Wu 2022 spring but class is not listed so I'll say something here.

Don't take his class.

I got wrong on part of a small hw question. It got me 10% off the total hw. Prof doesn't use gradescope, so you have absolutely no idea how you got your points off. I went to ask TA for the correct solution, TA said go ask prof. I went to the prof. Prof said go ask TA.

Quizzes are also fcked up. Extremely unclear question prompt with millions of possible interpretations. Thought it's completion grade, it doesn't help to throw random garbage prompt just to waste students' time

I didn't really go to class so I can't say much about Prof. Wu except that he once played Animal Crossing music during our mid-class break, which is pretty sweet. The course content was presented in a very clear way in the lecture slides and the textbook. These course materials were enough for me to complete the homework and open-note quizzes and do quite well on them. Like others have noted, the labs were kinda pointless. If you get a TA who helps you through them step-by-step, you should be fine; if you don't, I recommend making friends with someone who DOES have a helpful TA or joining a GroupMe chat for the class. The midterm and final were not too difficult, but the wording of the questions can be tricky. I finished the midterm with extra time left and made the mistake of submitting early. If you have time left on either of the exams, use it to go through every single question to ensure that you weren't confused by the wording. There are only 20-something questions, where some questions are worth more points than others, so missing one can be the difference between an A and a B.

Exams and quizzes were generally not easy. You need to watch every one of the discussion videos and to browse campuswire twice a day in order to finally get the details for your assignments clear. (what is desired is often not well specified in the spec) Despite all these, the course has really generous curve.

Stupid formatting requirement

“Could you give me some advices on this professor?“ Here is my answer. Just DON’T. Just DON’T. Just DON’T. At least don’t do it when you got options, like any kinds of options. I took 102B this spring with Wu, and these are my thoughts about this nonsense.
First of all, the grade standard of homework is totally ridiculous. I am not sure it’s the problem of grader or Wu. I did the homework totally the same as the grader’s posted answer, and I lost points. When I talked to Wu with the problem, which is frequently happened, he just told me to find TA. And then when I go to TA, TA told me to find Wu first cause he is also don’t know the answer. And his homework is really hard to understand what he is asking. He almost never taught us about R in the class, but his homework is all about R.
Secondly, his teaching quality is the worst I’ve ever taken before. His speaking is ambiguous and stuttering, just the same as his PowerPoint. You have to listen very carefully to get the idea of his lecture. And even if you do, it still chaotic.
Most importantly, the final is totally BS. He said several times that the final would be like the quizzes. But either he’s out of his mind, or I’m out of mine. It’s like dropping from heaven to hell.
All in all, I will never take his class again as long as I am alive.

Professor Wu was one of the sweetest professors I've had here. The exams and material aren't necessarily challenging, but there are quizzes, labs, and homework to stay on top of. Overall, if you manage your time well, this class ends up pretty easy and most people are successful in it. Would recommend taking this class with him.

The class material itself is not difficult, but it is also not very interesting. Wu isn't a bad lecturer but he also isn't reinventing the wheel when it comes to it either. TA's walked through every single lab and homework. Tests are not difficult. If you stay on top of it, an A is definitely possible
