I can't not even explain how bad this teacher is. I can't understand him, he writes like a 2nd grader, he won't tell us how many/when our midterms are. There are no practice test. He puts in no effort to help you do well or learn. I actually like math but I have never dreaded a class more.

I am honestly livid. I took him for 34A last quarter and I will tell you right now you will not learn a single thing in lecture. Nothing he says makes sense because he reads from the textbook but never says what we are working on. EXTREMELY disorganized notes and I teach myself the material. I got a C in 34A, just barely passing.

NEVER take this professor, first day of class I couldn't understand what he was saying because of his very heavy accent and his handwriting is TERRIBLE. You have to rely on yourself to do your own work with YouTube videos or something cause this aint it fr. This man's laptop shuts down every 10 min like bro what the frick. I don't understand.

Professor Ye was usually unprepared for lecture. He was very unclear with his teaching and although he is a good mathematician, he struggle to communicate concepts to the class. Most people stopped showing up. He also didn't use Gauchospace so there is no way of knowing your grade at any given point.

He is THE worst professor of all time. He knows a lot about math but has absolutely no idea how to teach. The 2 midterms were easy but the final was a nightmare. Only about 40 kids showed regularly to a class of over 250. He is super unclear, goes off on class-long tangents, and doesn't communicate to the students at all. No way to know your grade

Actually I think professor Ye is a really nice guy, he is not give us really hard time on homeworks or midterms and finals. all materials he tested us were the things he taught in classes. He is really serious about teaching and willing to answer all the question(you just have to ask!!!!)
