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...

Honestly for calculus, I would recommend taking him. His midterms and finals are very simple integrals that you can solve. The final was a bit hard but does curve up the class which helps a lot. His lectures were sometimes confusing but honestly he is a very good professor. Just study hard and go to CLAS or your TA if you need help. His OH help too

bad lecturer. a little bit of a language barrier as well. tries to be funny and draw really good graphs but it just wastes class time. not many resources to help you learn aside from a confusing textbook. he isn't rude or anything just a mid prof.
