Brown is an awesome professor! I am taking his math 131A this quarter. I know this is one of the hardest math classes for undergraduates, but he really did very well. Effective lectures, clear hand writing (not like some other professors....). The grading system is: The quizzes count 10 percent, each midterm counts 20 percent and the final counts 50 percent of the grade. usually there are 5Qs each midterm, 2 from book (def,theorem pf,etc.) 2 from HWs (exactly same, and his HW is not very hard, you can always find the solution from the book via internet...)
quiz is one of you hw questions, exactly same..
take him! this could be one of your best classes in UCLA
