legendary. Guaranteed A if you go to lectures and put in a little effort.

took his 104A earlier so take this 104B again. getting a good grade is not easy when your TA is tough, but prof himself is not bad. hw is reasonable. if u skip his class, dont skip the review session. the grading policy is so nice. the "drop the lower mid score" literally saves my life. //will write another comment when i finish his 104c.

Prof Xu Yang is very nice and patient. He has review sessions that help us prepare for mid & final, which is SUPER helpful. drop the lowest for one of the hw & one of the mid.

Literally just used another professor's lecture slides and notes.

Very heavy accent and does NOT care about his students. Just keep talking and talking and assume everyone knows what he talks about.

Professor Yang communicates with the students often with emails, his lectures were straight-forward and I felt like I had a deep understanding on the content, and the exams are challenging. I strongly recommend for Math 3B.
