Lectures are just repetitions of the topics covered in the pre-lecture videos, so the lectures feel really redundant. I studied for 2 weeks doing all the available problems multiple times and even generated new ones. Still felt really unprepared for whatever that final was. passed tho

If you're looking for a professor who is more concerned with his status within the Physics department than he is with working with actual students, you've found the one! Be prepared to study with very minimal resources and the possibility of complete curveball exams where he ramps up the difficulty to "even out the curve"...

If you want a good GPA, avoid at all costs

Take Geller if you want to make your life difficult. grade is HW and 2 exams. The practice exams are not at all similar and you're going to see questions you've never seen before in your life. It is VERY DOABLE- hw is ok, exam is mostly questions u can figure out, but so much worse than it should be. Save urself the Geller bs- take Freund.

The midterm is easy, but the final is hard. He will try to mislead you with the formula sheet, giving many equations, but you will only use half of them. Ask around to find out what is important. The hardest part of the class is finding out what to study and finding practice problems. Started the quarter off by talking rudely about Prof. Freund.

. He doesn't have the etiquettes a UC Professor should have. Be more accessible to students.

He was okay but not as good at explaining a lot of the concepts as Freund. Also he assigned us a lot of lecture videos to watch but they ended up being very redundant to the content he covers in lecture in person.

Every time I left lecture, I was unsure about what Geller wanted me to take away from it. The final for 6C was the hardest exam of my life. So many question types that were unlike anything we have seen before. Practice tests don't really help you. The Achieve homework is a nice grade buffer. Definitely take Freund if you can!

Professor Geller is a very interesting and funny lecturer. His class is fascinating and a fun GE to take. He is passionate about the subject. There is quite a bit of textbook readings and weekly homework assignments, but overall, an enjoyable class.

great lecturer, loves to talk about astronomy. Very friendly guy, but gives a lot of textbook readings and assignments on a weekly basis. All in all, not that challenging of a class. Enjoyable GE.

This class can be a lot of work for non stem majors but is very fascinating. He is super funny and very passionate about all things astronomy so his lectures are always interesting. Exams are multiple choice and very straightforward. He is happy to go down any rabbit hole about physics.

Honestly I'm not sure why Geller gets so much hate. I find him to be quite entertaining and his commentary in his lecture videos makes me laugh. He is a good professor and I feel like I've learned the most physics than the other two classes in the series. I strongly dislike physics but I will say that Geller definitely does keep me engaged.
