Spring 2022 - Going to be blunt, and a little rude. This professor should not be teaching, isn't mentally capable to teach anymore at this point in her life. Constant typos in important graded materials to the point where it looks like it was written by a senile person. I wish I didn't buy her textbook, as I didn't use it once the entire quarter. I cant remember if it was needed to access cognella (literally a ripped off version of ccle software). Doesn't care about the wellbeing of students at all, is not consistent on assignments. The way her assignments are valued changes on a weekly basis. If i had to guess, they moved professor sanchez to online asynchronous cause the students who had to suffer her in-person classes complained to much. Frankly I dont think she should be teaching at all, and it appears like the TAs do all the grading for her anyway. After taking this class, I still feel like I have learned nothing about stats. I dont know my final grade yet but im expecting anything from a B to an A-. I would have rather taken the class in person with a competent professor but they were not available to me. I wish I had waited to take Stats 100A instead. DO NOT TAKE THIS PROFESSOR. You are not going to be the top 1% of the class who gets an A. If you think you are, then you probably value your education, which in that case DO NOT TAKE THIS PROFESSOR since you will learn nothing. I am fuming that I spent money to "learn" in this class frankly, and she should use the money she has from scamming the university and their students to just retire.

Fall 2019 - DO NOT TAKE THIS CLASS WITH PROFESSOR PAIK!!!!!!! I read all the reviews about how easy the midterms are and how this class was such a breeze but it was not! We base the entire class off his shitty book, in lecture he literally reads the same thing thats in his textbook then waits a couple seconds and thinks that by giving us those few seconds we are going to magically learn what he just read?? The class in not based on if you did the work/process correctly, it's based on if you get the correct answer which shows how lazy he is in grading the exams!!!!! The exams are all multiple choice and a lot of times theres one tiny mistake that changes everything and you get the wrong answer but no partial credit just a big fat zero. While he does let us use open book and open note, it's kinda deceiving because were on such a time crunch so going through the notes/book is a hassle and wastes a lot of time. I ran out of time on every exam. Overall I was very frustrated with this class. I've had bad professors but I've been able to teach myself the material and be successful in the course but not with this class! He did not give us the materials to succeed! He based everything off his book and slides which are basically the same thing as the book and there were very few practical practice problems. Take this class with a better professor! I chose Paik because of his past grade distributions but it backfired on me. I have multiple friends who were not successful in the course so I know I'm not alone on this post

Spring 2024 - This was Professor Wang's first time teaching Stats 100A, and I think it showed. Lecture was incredibly dry, and she wasn't the best at explaining how to apply theorems to problems. Lecture was way too heavy on derivation, and not enough on problem solving or thought process or applicable examples. This led to HW being really confusing at times, but overall they weren't too bad. Tests were relatively easy, with a chill midterm and take home final. Overall, I found this class very mind numbing and boring, but it's not that hard to get a good grade. If all you care about is getting an A, I would take this class with Wang.

Fall 2020 - Note: This review is for Fall 2020, a quarter conducted remotely for this class. STATS 100A with Professor Wu was a straightforward, easy class with little work outside of class time. Professor Wu uploaded his slides to the website before the lectures so that we could follow along, but he did mention some things during the lectures which were not present on the slides. I thought he explained things relatively well, but the class was a little slow in that he would spend the first thirty minutes of class reviewing the material from the prior lecture. This was the main drawback: I feel as if we could have gone more in depth in the material discussed or gained more breadth on other topics. The graded material for this class was relatively simple. The homework assignments closely mirrored the lectures; some of the problems were verbatim from the slides or extremely similar (i.e., the only change was the numbers used in the equations). The midterm and final were pretty easy as well: they expanded a little bit on the lectures, but most of the answers could be found after perusing the lecture notes (the exams were open book). TL;DR: Regarding grades, the class is a breeze. The material learned is easy to retain, but I feel as if we could have learned more.
