Prof Li's lectures are concise and easy to follow, course material is relatively easy. However, his class is so stressful. He goes all the way to make you as stressed as possible. The midterm and final exam questions were not hard, but the time given is unreasonably too short!! He gave us 2 finals. Avoid him for your own mental health

His lectures were okay, but he didn't seem interested in helping students. The midterm and final were hard not because of the kinds of questions, but because of how little time he allows. On top of that, he completely ignored students in the 2 weeks before the final. No replies to emails or Piazza posts. He was even disinterested during his oh.

This class is very time consuming and difficult. Challenging python homework on top of weekly homework. Midterm was a big time crunch, 2 finals at the end of the quarter, one limit time and one take home. The take home exam took me 8 hours to finish and all the tests were graded very hard. Attendance system was a disaster. Finished at 93% exactly.

Ok look. Do not take any classes with him. I spent 3 days doing the final and I am not over exaggerating. If you can take any of his classes with a different professor, PLEASE do it. He was so bad and hard for no reason whatsoever. His grading scale and grading methods are very arbitrary and terribly graded. He is a sweet guy but an awful professor

Was .25% away from the next letter grade, but he was being very stubborn as he refused to give me any sort of extra credit whatsoever. He is a very strict grader and he refused to listen to me. The tests are harsh as they are very heavy and there is a lot to do in a short period of time. I got severe depression and anxiety form this class.

I cant really complain about Prof. Li too much. At first I thought the homework was heavy, and the midterm (44/50) was tricky for 75 mins time. But the post midterm chapters on Markov Chain were a breeze and the finals were reasonable, especially the take home(94/100). On top of that he curve our final by 5.5 pts, midterm by 3.5. Great professor!
