    118C . Yan Z X 9 Months Ago

    Honestly the class was a joke, we just used Rudin but the lectures were just him reading the theorems and telling us to go over the proofs on our own time. The homework was super easy and he gave up part way through the quarter and turned this into a 6A class. It was super easy but you won't be learning anything from any of his classes.

    Math108a . Yan Z X 9 Months Ago

    Dude might be a genius, but very dismissive and overall one of the least professional professors I have ever experienced. Class was easy enough but I will never take one of his classes again.
