I want to start off by saying I have never taken a stats class before, at first I was extremely nervous to take this class with this particular professor due to the amount of things the professor did to prevent cheating. Both exams were on respondus and we had to have our phones on zoom with the camera directed on our hands. As someone who already gets anxiety during exams, this policy did not really help ease it, I will say I was much more calm during the final though as I knew it was not as bad as i had initially thought. To break the class down, lecture attendance counted as extra credit (max 1%) and were recorded/uploaded to ccle, at first the professor would only leave the lectures up for 3 days and then we were not allowed to watch them, but for some reason he just removed this restriction after the midterm. Labs/HW were both worth 20% of our grades (so together 40%), the hw's were pretty easy, labs I hated simply because I did not understand the purpose of them, grading will depend heavily on your TA. I personally had Jireh and he was amazing at explaining concepts and was an overall very good TA. The midterm and Final were both worth 30% each, and were both mc. The final was not cumulative and was everything after the midterm, both exams were not focused on calculation, rather they were heavily conceptual. Overall, I think I stressed about this class a lot more than I should have, professor Wu does have a very monotone voice, but he is very good at explaining most concepts and would try to interact with the students during lecture. I definitely think that this class was very fair, after taking this class I appreciate the security measures implemented to prevent cheating, as I think my final grade would have been a lot different if they weren't. In all, the best way to describe my experience with this professor was fair, it was not super easy but if you put in the effort it should have not been extremely hard.

Professor Wu's voice is a bit monotone, but his lecture is clear; he posts slides and lecture video, which align very closely with the textbook. Prof. Wu is also very nice, cares about student learning, and occasionally makes quite funny remarks. He replied to emails pretty quickly, was helpful in office hour and gave curve in the end to students who showed progress throughout the quarter.

The labs give a gentle introduction to R and RStudio and should each take about an hour or so each (I assume we truly start utilizing R heavily in Stats 20). You should be fine as long as you follow your TA's guidance and read the lab PDF carefully. The homework assignments are not computationally difficult (the applet does most of the work); rather, you should focus on having a clear understanding of the concepts (when to use what test; the necessary conditions to use it etc). The exams are all multiple choice questions, 2 hours, in Respondus Lockdown Browser (You can bring one piece of "cheat sheet")

Jireh Huang is a very helpful TA; he is good at explaining the concepts clearly and concisely and uses the discussion before assessments to help out with any last minute clarifications. Jireh also responded quickly in Discord when I was confused or had conceptual questions. My biggest impression of Jireh is his dedication to student learning. When he lost his voice, he still typed everything he wanted to explain and clarify in discussion session so we were prepared for that week's lab.

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 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 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

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

I'm a STEM major and I LOVE math but oh my god do not take this class with this professor. We were supposed to cover 10 units in the course and only covered 2. ONLY 2!!!!!!!!! His lectures were all over the place and half the time when students asked questions, he didn't know how to answer them and this is a BASIC STATS INTRO CLASS. He was not an accommodating professor at all and for being someone who has gotten A's my whole life alongside my friends who were in this class, we all got C's because he asked questions on the midterm and final that we never covered in class. I even emailed him after the final and questioned if he would curve the score because everyone got a C or below and he said he wouldn't do so even though we got tested on units we were never taught. I feel bad for stats students who needed to learn the rest of the 8 units to prep for their next stats class since we only covered 2 units. I literally am so infuriated by this professor and the fact that he never apologized to us once for not doing his job and we were the ones on the back burner. Exams were on respondus with a separate camera watching our hands. The questions were very conceptual so even if you have good stats knowledge the questions are tricky, especially when you're being tested on topics that you weren't even taught how to do. Please please please go with any other professor.

“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.

Very mid. Prof wasn't that good. The slides alone are honestly as good as lecture (or better). The class is very closely related to Math 151A like root finding, floating point (which are good topics), then it goes into R's classes which are different from C++ and regular ones, so it's pretty annoying. There is some useful data manipulation and regex.
The homeworks were fairly long. And the tests are pretty tough. Our final had ~40% average. We did obviously have a fat curve. But he says the tests are similar to the quizzes, which is a lie. They are scaled in difficulty by a lot and more specific on details, I see they are similar but tougher. The cheatsheet imo is pretty important, and it's crucial you have a good one.
The math and programming part is nice, the R classes portion is weird and annoying.
