34B . Ye R A Month Ago

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.

DO NOT TAKE THIS PROFESSOR UNLESS YOU ABSOLUTELY HAVE TO! Lectures are useless & seem to go on for years. There is no structure & nothing is explained. He just goes up there & rambles for an hour. If you do have to take this professor sign up for clas bc you will need it. Honestly, do not know how he is a professor. good luck if you take his class

Professor Ye is the most disorganized professor I have ever had. He had no consistent train of thought during lectures. The syllabus wasn't posted until at least two weeks into the quarter but I guess it didn't matter because I had to self-teach the whole class anyways. Midterm was easy, final was the hardest test I have taken. Avoid him if you can

Final was 53% of the grade. Do not take his class. You will have to go to CLAS and also teach yourself the math. Final was not like the homework. Also a lot of homework.
