Absolutely horrendous. Lectures are a joke and not prepared at all. Almost everyone gets an A because he gives out a practice midterm that is similar to the test, but you inherently don't feel like you're learning anything at all along the way. Great to see this guy gone from UCLA.

I am sad to see Dave leave. He was a great professor who inspired students to learn for the sake of furthering one's self, not to learn to get good grades and be a bitch to college/your GPA. If more professors were like him, the school would be a better place especially for south campus classes. Great man, well progressed lectures, and such a cool and awesome dude.

I have no idea why so many people praise him.

I have to say he is 100% a nice guy and he is very concerned with his students' learning, but he cannot teach well. That is a fact.

1. His lectures are extremely unorganized. He doesn't have a clear schedule and he never uses notes to have some easy numbers to work with. So many times, the class becomes an over-complicated algebra class s.

2. He does not usually talk about definitions. So the outcome is: after a whole class, you had no idea about what he talked about.

3. He covers materials that are not required and does not cover materials on Math Department's syllabus.

e.g. He skips Chapter 2.2 and the whole Chapter 8, but covers 115A material: vector space and inner products.

So after this class, everyone gets an A, but learns little.
