Okay the other reviewers are right. Eric uses a big notebook all the time from which he copies notes, so his lectures can get boring sometimes. But he does offer extra credit during a random lecture to reward attendance. He is very willing to help you after class and in his office hour for all kinds of questions. This is very important for 131A. Eric's exams are pretty fair. All you have to do is to memorize important definitions and nearly all the theorem proofs. This sounds silly, but this is what 131A is all about. Overall I'd recommend him for 131A, plus he's a good looking stud.:)
