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

Took 33B, 131A with Goldbring. He explains things well! He's also helpful and approachable. In 131A, the exams were similar to the homeworks. In 33B, there were a few curveballs! But study the hw problems and class notes and the exams should be okay. BEWARE, in 33B, he gave an insane amount of homework. It's good practice though.

I ABSOLUTELY LOVED BETSY! Going into this class, i was really nervous. I'm a math/econ major and lets be honest, not many people are fans of the really proofy classes. And this is one of them. I took Betsy her first quarter as a professor, she was relatively new, but SUPER NICE! She spent a couple of days making sure that we understood the 'lingo' of the proofs and negations and simple stuff that you would think wasn't necessary but turned out to be very helpful. When she did proofs in class, they were always different from the book. Some people could see that as bad, but it helped a lot because you got to see 2 approaches rather than just 1. She was thorough and when people asked questions, she would spend the time making sure that you understood it. Obviously, this class is an upper div proofs class. So no matter what GO TO OFFICE HOURS! The TA's and the professors. She was very welcoming and if you went in with started homework and she saw that you got the basic idea, she helps you and explains what is working and what isn't. Plus she was just a really cool person to talk to. I still keep in touch with her and i took her class a year ago. As for the midterms (which i'm sure is the reason you are reading this) the first was really fair. We hadn't covered too many topics and i got an A on it before the curve, with some serious studying of the proofs we covered in class. The second one, we had at least 10 topics to cover but there were only 4 questions on the midterm. Let's just say no one did really well just because there was only 4 topics covered out of the 10. The final, I'm not going to lie, it was difficult. But it was doable if you learned what to study from her midterms. She's always very fair and if you ever have a question about something she'll answer it during the test. One thing I definitely noticed is that she likes to go over proofs in class that are relatively difficult, but really important. Those were the ones taht would end up on the test. She would probably do around 50-60 proofs in class, and at least one of them was on the test if not something really similar. The class itself is difficult, so going in you should know that. Betsy is a great professor and really helpful with ANY AND ALL questions you have, in class or outside of class. I would take her again in a heartbeat!

I had him for both Math 61 and 131A. _____ For Math 61: I had friends who both liked and disliked this class. I personally thought he was clear, concise, and effective. I think the issue with Math 61 is that the class generally is full of CS majors-- who in many cases are better at math than math majors, for whatever reason. So the competition was stiff, which rubbed some people the wrong way, particularly since Math 61 has a reputation for being an easy math class for a lot of people. I studied a fair amount for tests but kind of half-assed most of the homeworks, and ended up with a B+, which was generous considering I did average on almost everything. _____ For 131A: I was warned beforehand that 131A was one of the most challenging math undergrad courses. It certainly wasn't easy, but taking it with Unger was a smooth ride the whole way through. Honestly, he has a knack for explaining more abstract concepts or complicated definitions in a way that almost anyone can understand. I think I was able to appreciate his skill as a teacher more as a student in this class, compared to Math 61. He also didn't hesitate to draw diagrams to help explain certain things, which was always helpful. _____ In both classes, one cool thing he did was post study guides for tests so that we'd know exactly what was being tested, and to what extent we had to know certain things. Exams in general were always moderately difficult. Usually a range of easier questions (sometimes just definitions) to more difficult (asking you to extend your knowledge beyond what you studied or apply it in some way). Nothing totally out-there though. Oh yeah, he's a pretty friendly guy too, which is always a plus. Overall, I'd definitely recommend him. Go to class, and put time/effort into the homework, and you'll be fine.

David is a great math professor. He does not limit us to problem solving yet encourages us to think outside of box. His classes involve stories and history of the course materials which are really interesting. He's really concerned about students and made problem set session for us from week 6 and on. He's one of the best math professors that I have had at UCLA.
