geller is an awesome prof and most of the negative reviews on him are people not wanting to put in the work for his class. physics is a difficult subject, he warns you AND tells you how to succeed on the first day. listen to him. i didn't in 6A and almost didn't pass, now i'm in 6B actually following his advice and i have an A.

Not too hard but you should go to lectures. Homework is a bit difficult but often harder than the tests.

Pros: I left his class knowing more about physics than I did with freund. HW is worth 40%, only one midterm and a final. Lots of in class demos Cons: Likely more effort than freund, and things you are expected to know for exams are less straightforward. More HW than freund, exams are a little harder, and less practice problems done in class.

This guy loves achieve, sometimes assignments almost every day of the week. Basically taught myself through the pre-lecture assignments.

He was fair most of the time! Midterm was very easy and always tries to cut down on material in order to save time and make the students' lives easier. His final was very hard unfortunately but just study a lot and you'll get well above average. Do the practice problems he posts and go to office hours. I wouldn't take him again but he was alright.

Unfair tester, totally screwed over the class with the final in 6B and 6C apparently. Just take Ernest Freund, he actually knows how to give a fair exam!
