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.

Winter 2021 - Grade Composition: 45% Midterm + 25% HWK (Assigned weekly from Week 2 to Week 10; 9 in total) + 30% Final The Professor was very willing to help during his Office Hours. He did give clues to challenging homework problems. The distribution of easy, medium, and hard questions on the exams was around 50%, 30%, and 20%. The only thing I disliked about this class might be that my TA could hardly speak English. I simply skipped discussions and hardly took advantage of any resources from her. Fair Professor and pretty tough class for me, so definitely requiring some hard work.

Spring 2022 - Avoid this professor. All other reviews for 170s were during online quarters due to COVID, ie 24 hour exams. I took this class fully in person with timed exams, and I would say it is the worst math class I have taken here (even compared to math 115a in person). The grade is only composed of quizzes and exams, where quizzes are 24 hour and easy, but do not reflect difficulty of exams and are very surface level. The first midterm and the final were completely unreasonable in terms of difficulty. The mean for midterm 1 was around 50. He gives optional homework which are just book problems and does not provide any solutions or explanations to check with, so if you don't have Chegg you are out of luck. His lectures/lecture notes are just the textbook summarized and often contain errors in formulas. Even if you were to solve all textbook problems (as he recommends for outside study) you would not be prepared for his exams. He also does not plan to curve the course at this moment (I am still waiting for my grade). It is just appalling that this lazy professor managed to make a class which is normally regarded as one of the easiest math upper divs a complete nightmare.
