Awesome lecturer, super helpful, taking 160b with him was one of the best experience I've ever had at UCSB. UCLA is lucky to have him.

Best prof I've ever had

worst prof I've ever had

I highly recommend not to take his class because his lecture is unbelievably unhelpful and he gives no hints for homework. Unfortunately, if you need this class, you should find classmates to cooperate homework.

One of the worst professor I've had at UCSB as a stats major. Homeworks and assignments are difficult, and he does not provide a lot of help in lecture or during office hours. TAs are your best bet to pass the class. PLEASE AVOID IF POSSIBLE, just take it another quarter.

Avoid this guy at all cost. Lecture doesn't correlate much with exam. Doesn't know how to explain things not clear. Unclear grading criteria.
