Fuck Guani Wu. Easily the second worst professor I've had at UCLA (only slightly beaten by Gabriel Freiman) which is saying a lot considering the race to the bottom at UCLA. Lectures are completely incomprehensible with Wu spending significant amounts of time either reviewing previously discussed material or going off pointless tangents. We also ended up not covering all the material (Gibbs sampler). Homeworks were often vague and confusing. Weekly quizzes are required which require the use of Lockdown browser which makes reviewing the quizzes inconvenient while doing nothing to deter cheating. Exams are complete bullshit - Wu gives you way too many questions, most of which involve concepts not taught in lecture or homework. More specifcally, the midterm had around 25 questions requiring a lot of calculations which was a time crunch considering we only had 75 minutes to do the exam. The average for this exam was in the 40s, and Wu doesn't let you review the exam outside of office hours. Meanwhile the final was filled with very theoretical questions unlike anything covered in homeworks, quizzes, or the midterm. I expect the average to probably be even lower than the midterm.

Tl;Dr Don't take this class. Anyone that thinks Guani Wu is an acceptable professor is either delusional or a massive UCLA dick-rider.

As someone who took AP Stats before this course, it was pretty easy all things considered. There is very little computation in this class and the course is very much regarding the theoretical/practical side of statistics rather than the formulas. We never even used a z-table in this course. All in all, it's definitely not a terrible class if you have prior knowledge.

I'd also like to interject that I took this course as a GE because I'm not a life science major, so I didn't really have as much reason to get too invested in my grade here, but regardless I did give it the best effort I did and scored well on the tests.

The labs and homework are fairly manageable. I managed to finish them in about an hour or two each, but they still did a good job of teaching the basics of R and statistics.

All in all a good course. As for the professor, he is an acceptable enough lecturer given the trying times (this is during the COVID quarantine), but he did a good job of clarifying things in class and gave engaging examples of what he was teaching. Whenever there was downtime during lecture, he would converse with us and just ask us how we're doing and what our student lives are like. He really seems like a nice and personable guy. Also, he was very accommodating when I ran into tech problems during the course trying to take the exams. Great professor.

Also, like anyone who has taken a statistics class on UCLA and left a review on BruinWalk, I am obligated to bash the TA Jake here. He actively disincentivized me from going to discussions because every time I did I felt like I was being belittled. The syllabus encouraged us to work together on homework so long as we weren't just pasting answers without explanation and we would often share solutions after the homework was due via GroupMe. (There was an official Discord server for the class, but sometimes we just wanted to talk as students and help each other through that rather than using the Discord which often felt more formal.) This happened after I left the group chat, but he apparently joined the group chat just to tell us he was "appalled by the number of academic integrity violations." I didn't follow the GroupMe that actively, but unless there was a major breach during the final, I don't recall anything of the sort.

Professor Wu and the TA struggled a little with the online format, but that was to be expected for professors and students alike. Unlike some other unsympathetic professors, though, Professor Wu was obviously doing his best to create a good learning environment and be caring for his students.

Nonetheless, there were some inherent issues with his implementation of the course. For one, the Stats departments obsession with non-collaboration on anything was incredibly annoying. Not being able to work on homework together was tough and isolating. The quizzes were hard and it was unclear as to what topics they were covering. The tests had extremely tough wording at times, and the homeworks were very stressful at points. Most annoyingly was the specificity of the homeworks. Having to name files a certain way or making sure the files were knittable (which an easy solution was never explicity given to this problem) or automatically have 50% of the grade taken off was harsh to say the least.

The use of campuswire helped a lot. The TA Oonyambu was very responsive, albeit a little short with answers sometimes (see also: the way Jake answers questions but a little less harsh). Overall, I would take this class again in its second, COVID-tested iteration, which I think would have a lot less kinks than my session had.

Over the global pandemic this professor was not leniant at all. We all had to use a respondus lockdown browser AND a zoom during our midterm. We were told to turn down the zoom but they were sharing corrections to the test questions that many people didnt see. Furthermore the practice tests he gives us were so easy that everyone got 100 but bombed the midterm. The professor and the TAs especially were not flexible considering the stressfull situation of COVID and online classes. There is no option for makeup work and I was overall very dissatisfied with the course and the professor.

I don't know if it was the professor's idea or the TAs but the homework and labs are graded very strictly on accuracy. There are a lot of analysis and explanation questions, if you get the smallest concept wrong, you automatically get points deducted. Homework and lab are 40% of the total grade so that takes a lot of points of the total, making it impossible to get a fair grade. The class is not flexible at all and they are not considerate about the current situation of COVID. I don't know how the class normally is in-person but if you plan on taking this course when online, I highly recommend you take it with a different professor. The content itself is very easy and my friends who are taking stats 13 with another professor are not having the same problem as I had.

Extremely unengaging lectures, very uncommunicative and very unclear. Homework assignments are a guessing game of what he actually wants you to do because the instructions are extremely vague and unclear. Tests consist of multiple choice questions of randomly nitpicked details from lectures instead of actually testing your ability to code in R. Class averages were very low on tests. Would not take again.

This class may have had great ratings and may have been "easy" for the most part but the exams were horrible. The TA's were great but no one was super helpful even Wu. He made a typo on the exam leading to the wrong answer and would not even assign partial credit for it. There are other great Stats 10 professors with no exams and that are super helpful. Wu's exams are hard and his class is extremely boring. If you can take another professor, I would recommend.

Professor Wu is an understanding, nice professor. However, his lectures are really just not stimulating whatsoever. I found them to quite boring and poorly paced. We ended up having to rush through the last chapter leaving many students (including myself) confused.
The homework can take some time, but I found it to be fairly straightforward. The quizzes can sometimes have unclear wording, but they weren't difficult.
The assigned labs tend to stray from the lecture materials, but they're walked through by TAs so they're not that tough to complete.
I found the exams to be quite difficult compared to the lecture example problems and the HW questions. The midterm wasn't bad, but I found the final to be pretty tough. Luckily though, he's quite lenient on grading and applies some extra credit/curves while dropping the lowest HW + quiz grades.

All in all, Stats 10 with Wu is a class where success is certainly achievable, although the lectures and section material are mind-numbing and far from engaging.

Professor Wu explains the content really well. Midterm and Final are all MC questions. Labs and hws are easy.

Lectures slides are clear and informative. You might want to take notes on his lecture slide "doodles" during lectures, because they are important and will not be updated on lecture slides.

Homeworks and exams are tough. Although he meant well to push students study hard, assignment policies are harsh and he explicitly forbids collaboration. Respondus Lockdown Browser is mandatory for exams.

Heads up for homework due date changes and check CCLE daily. For Winter 2021, he moved the deadline of the last assignment several days ahead without informing students.

It absolutely disrupted my review schedule for another class' final . Some students I know ended up pulling all-nighters to cram this last assignment. Hopefully this will never happen again.
