Summer 2024 - I took the summer session so the content was accelerated but overall was still very manageable. No textbook is really needed because the slides copy-paste the most essential information and the z, t, and chi square tables are all provided on exams. I will say that this professor struggles to explain concepts clearly, and focuses a bit more on proving theorems (not tested) than actual application. I think the best strategy to get a good grade is to review the lecture slides then use the homeworks to test your understanding. The exams are the same difficulty level as the homeworks and there are few curveball questions. I'm pretty sure he curves depending on the grade distribution. Concepts from 170E are pretty much the foundation of this course so brush up on that before starting, as he will expect you to know poisson, gamma, beta, and chi square distributions, their expected values and their pdfs are fair game.

Spring 2024 - I often got lost in the lectures and found them very hard to follow. He posts his notes but I found those confusing as well (and so have other people in the class). I feel like he didn't give us enough homework and he ended up testing us on things that we've never even practiced. Since his lectures were confusing and we barely got any homework I wasn't really sure what to study for the final. *He only gave us three homeworks for the entire quarter (each consisting of 5-6 questions). He's a very nice guy and will try to help you if you ask but I just felt like we didn't get enough practice so I was lost for most of the quarter.

Fall 2020 - After reading all those "great" reviews for this professor, I thought its a good choice to take Math 170S as one of my elective class, but I can't describe how awful this class was. Imagine someone just reads you the lecture note pdf that is already uploaded, word by word in slow motion and leaving the questions unsolved, then having a quiz every other week which takes so much time with only 2hr limit time. (Btw if you f*ckup your midterm, quizzes will worth 50% of your grade so really be careful on quizzes). Finally both midterm and final was the worst and impossible to pass since the instructor will be grading it himself with absolutely no partials. My advise: This class is far away from being easy and useful, so don't waste your time on taking Math 170S with LYU and try whole quarter to pass the class, either take someone else or ovoid probability and stats.
