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.

Stats 10 is generally an easy class and Wu is a pretty good prof to take it with. His lectures aren't the most engaging because his voice is monotonous, but he really paid attention to the chat and always answered our questions. His lectures are on slides, which he posts on CCLE. He does clicker/poll questions during lectures for participation EC (up to 2%). Quizzes, the midterm, and the final were all multiple choice. Before both exams, he posted a study guide and gave us a practice test. During discussions, TAs basically do the lab with you and they go over homework questions. For this quarter, Wu made the final optional, dropped our lowest 2 grades from homework and quizzes, and cancelled our last lab, so he's really accommodating and willing to empathize with students.

I took AP stats in high school, so I already knew the material, so the class was really easy. I only attended lectures because of the poll questions, which gave you 2% extra credit at the end of the class. The midterm was incredibly easy, but the final was hard. However, due to the protests and blm, he made the final optional and changed the weight of the tests. The homework was easy, especially since the TAs basically did the work for us. The weekly quizzes were also easy, and he gave us ample time to do them. The only part I hated about the class was the labs, I still don't understand why they are necessary to the class, but at least the TAs walk you through them step by step.

If you want an easy class with a chill professor take this class with Wu. The info isn't exciting, but Wu teaches in a clear way and cares that his students are learning. He also wants students to succeed, so he ended up dropping multiple quizzes, homeworks, etc. The TA walks you through all the labs and gives you answers to all the homework per Wu's instructions. Take this class and if you put in just a bit of effort, you will get an A.

It doesn't get better than Professor Wu. This guy is the nicest, most friendly teacher I've had. He was so accommodating with the whole COVID situation, but tbh he didn't even need to be. Stats 10 really isn't a hard class. You get notes during the tests and the quizzes weren't even timed. They are super fair when grading homework and labs and still drop your lowest grades. And seriously - Wu is the best.
