Bro just fired him

DISASTER. DOESN'T know how to teach. DOESN'T know how to make clear slides. DOESN'T know how to grade (highest score for the final project is 84%). The ONLY thing he knows is how to make easy concepts more confusing. One of the worst stats profs I've ever met at UCLA for the past six years.

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.

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!

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.

I am honestly shocked about the current rating that this course has. Professor Wu is my favorite professor at UCLA and goes out of his way to be accommodating to his students. This course was challenging and you will need to work hard, but it is by no means impossible. Professor Wu has a more theoretical teaching style, but if you have questions and you go to office hours he will take the time to help you understand. He really is a great guy. Good luck!

Nice guy but workload is heavy (each hw took anywhere from 5-15 hrs) and exams are brutal. Curve is super generous so most people get decent grades but you don't really know your standing until the end. Class was hard but not impossible, just took a lot of time.

This can be considered as a general comment for the entire 102 series taught by Professor Wu. I had A-/A/A for 102A/B/C.

To start with, Professor Wu is a really nice person, he often jokes in class and answers whatever questions students have. Having taken three classes with him, I guarantee you that he really likes teaching, and he is in fact one of the few Professors in the Stats department who wants to teach you something...

As for the class, I have seen many negative comments on Bruinwalk, and I was also worried at first, but it turned out to me that it's an easy A as long as you pay attention in class, read through his notes, do the homework by yourself, and perhaps ask questions in OH. I got A- in 102A bc it was online and I didn't really attend the classes much...

He focuses a lot on mathematical (or theoretical part of) statistics, so you will see lots of derivations, proofs and the math heavy stuff in his class. If you don't like the theoretical part of statistics, then you probably will suffer in Wu's class, and I would highly recommend you to take Miles Chen or other professor's classes instead. However, if you plan to pursue a graduate degree in statistics or go for academia or really want to master statistics, then you have to learn these stuffs and taking Wu's class will be truly helpful. I personally likes the theoretical stuffs he taught, so I enjoyed...But if you aimed for practical application alone, then nope, it's gonna be a nightmare like the other comments have detailed.

In general, I feel like the stats department divides into two tracks (application and theoretical) based on professors. Christou, Wu, etc. are extremely theoretical based; whereas Miles Chen, Lew, Mike, etc. favor application of statistics. (just some personal opinions...)hope helps

The most difficult concepts were taught right before the midterm and final. He does curve, but the exams were so difficult and I would not take them again. He is helpful in explaining the concepts, but the problem is that the difficulty from quizzes and in class examples to exam questions is quite a jump. I suggest looking up YouTube videos on how to do IEEE-754 conversions (extremely helpful) and any of the algorithm content.
As for the homework, they were mostly manageable, given that you go to office hours (his or the TA's) and get help. Note: you can't work on the homework together, so office hours is the only way to get help. Also, you don't get to drop any homework assignments. There was one extremely difficult homework assignment, so I suggest starting on homework as soon as possible so you can get help right away.
