He is happy you go to his office hour but I do not he can teach the text clearly although the book is written by him. Sometimes his logic is misunderstanding.

Since he wrote the book, it was obvious that he knew the material really well. The approach he takes really eases you into the material that is so different from past math courses I've taken. Section is twice a week, which REALLY helps. Homework is manageable and tests are fair. If you take Math 8, take it with him!

gerstein was a pretty good prof. he explained a lot in class and gave pretty decent lectures. tests were challenging, but fair, and there was a good curve. not too much hw- its helpful to do it anyway.

Took him for a class intended to prepare math majors for UD classes. He expects a lot, and the class itself is difficult but having section 2 times/week and attending office hours is helpful. He is difficult at times to follow but not terrible. From reading other reviews, my feeling is that he teaches more advanced material better.

He cannot teach. His lectures make no sense. Go to CLAS instead of lecture and the tests will be pretty easy.

loved him!! he's really funny, and a little random but that makes lecture easy to sit through. the material is not that bad once you get the hang of it.

Great teacher. The course was very coherent (he wrote the book, all homework was from the book, ect) and tests reflected course material very well. Some students find the course hard, I donno, I didn't.

Super hard class if you arent a super math whiz because the professor is very unclear and the tests are ridiculously hard and complicated and nothing like lecture or the homework

Gerstein is a fine teacher. He will test if you understand the material, not if you can do all the basic stuff. If you take his class be sure you understand everything that's going on and it's pretty easy to get an A.

effective teacher, well organized, and has lots of subtle jokes.

This professor is very good. I don't know about the previous comments, but if you take him for upper division, he is clear, helpful, and his tests are on material that you have seen before if you go to lecture and keep up on the homework. Very fair with grading as well.

i would rather stick a burning branding iron down my esophogus than sit through one more of his god aweful lectures. Avoid at all costs...even if it means the branding treatment!
