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.

Geller is a good professor. Not gonna change your life but he is super into astro and the class is generally fun and basic. He will not teach you the math, however there is very little math and you are probably fine if you know basic algebra and memorize what each variable means (T for time etc.) Just be ready to read and do constant achieve work

Geller teaches in a conceptual way. The pro about this teaching style is you're likely to understand how the world works better. The con is that learning problem-solving that matters for MT's is done on your own time. He gives you all the tools though. Know how to do the BP's (which aren't a lot) by heart and look at "good-student" notes. (6.75/10)

A funny dude but his lectures are very heavy, not to mention the huge study load which included homework and 8 sections of reading a week. His sections are where you are graded (weekly quizzes), which can mess you up because his grading is weird. Just not my cup of tea.

Amazing lectures, is always communicating with students about questions before, after and with emails. Essays in sections are usually straightforward, and multiple-choice exams. Geller also loves answering questions about random topics.

Lectures are packed with info but if you find astronomy, math, geology, etc interesting then it will be a fun but semi-hard class. Lots of reading, minimal math, mostly memorization.

professor seems chill, but too too much homework. As a summer online course, it takes about at least 3 hours per day.

Lots of homework which make up a lot of your grade which is super nice. Exams are hard but fair, if you keep up with the homework and do the practice problems he gives you will be fine. His lectures are super entertaining and interesting, always doing some fun demos.

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.

geller is very passionate about astronomy but you have to stay on top of the lectures and assigned reading or the concepts will be hard to understand. homework was online but easy, sections were essay questions (also easy), but some midterm/final questions were tricky and weren't covered in lecture.

Geller is a good lecturer but PHYSICS IS HARD. Test averages are pretty low, but Geller always sets reasonable curves to ensure the success of his students. The online homework is tedious, but a big grade booster and good for practice. Downside to taking Geller is you don't know what to expect on exams since he only has 5 practice questions total.

He's a chill guy. He loves Astro which makes it fun to hear him talk about things like the multiverse. Hw is through Achieve which is not my favorite but its manageable although kinda annoying. For a GE though, it does take a lot of time for reading and then rereading to study.

Class average for the Midterm and Final were 57%. Multiple students emailed him and his only reply was "you should try harder". The same class with Freund had an 85% average.
