Dr. Bao is a really nice professor, and he makes 33B really doable.
Very very lenient grading scheme.
8 weekly homework assignments, dropped the lowest 3, graded on completion.
4 quizzes, dropped the lowest 2.
2 midterms, dropped the lower one (in term of numbers, not scaled).

Weight:
Homework 10%
Quiz 20%
Midterm 30%
Final 40%

His lectures are OK. They get to the point, but they are not that interesting, at least not until the second half.

The quizzes and midterms are really doable. If you do the homework problems thoroughly, you should be fine for the quizzes and the majority of the midterms. On each midterm, there is always one proof problem that kind of throw people off in addition to an application problem. The application problem is fair game, so pay attention in class to the examples that he gives. The proof problem is not hard also.

I will strongly suggest that you take 33A and B together, as there are a lot of overlapping between the 2, and you can see some cool applications by using knowledge on both sides.

I've never met such a professor that left 4 of his lecture for other professors even 3 are in final week.

Very generous policy. Hard to understand, difficult subject matter, but tests are easy and he's a nice guy, albeit awkward in front of a class.

I took his 33B this quarter. His policy is really generous with 8 homework, 4 quizzes and 2 midterm and half of them can be dropped. Pro Bao is not that efficient and he usually makes mistakes in the lecture and even in the test. But overall, his is a good teacher and the exams is not that hard.
