No difference in listening to his recorded lecture from just reading his notes yourself, which are equally unclear. The recorded videos seem meaningless since he just transcribes his notes again and reads them verbatim. Not a good teacher.

Best math prof I had. His lectures are inspiring and deep. He makes sure you understand the main concepts and results. But you have to work pretty hard in his course. He demands a high standard. He really knows his stuff.

Hands down the best prof I ever had. He is inspiring, caring, and a gifted mathematician. A must for any math major.

class ok but quite possibly the most unhelpful prof i've ever had. Doesn't help in office hours and i don't know who grades the hw/exams but whoever it is must have some sort of learning disability. easy A for me in 104a but got a B in 104b even though i did much better on the hw/final. Yeah that makes a whole lot of sense...

He's a nice person but a bad teacher. He likes to make jokes and lighten the mood, which is appreciated sometimes. However it's hard to understand him through his accent and he goes through things very fast without fully explaining. I left the class, especially the second half, very confused and had to teach myself and have the TA help explain.

lecture so bad today im doing this mid class. his lectures are really confusing for topics that are not super hard. the tests are pretty easy but you have to self study. he tries really hard to be funny in class but is kinda mean to student
