Enthusiastic, clear, original, young, and knows his physics

The class was going great until the final. There were questions on topics I had never seen before, including modules that he skipped over and said we didn't need to know.

Students are expected to know a ridiculous amount of information w/o clear guidelines about what is actually tested. 5% of the lecture content is useful review/practice problems; the other 95% is tangents and demos that overcomplicate things. Instead of providing additional practice materials, he told us to generate practice problems using AI.

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!

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 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)

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 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.

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.

fun lectures that are both interesting and informative. cool demos. focuses more on the concepts rather than how to solve a problem in lectures, but it works b/c the textbook. tests are reasonably difficult. only dropped due to a medical emergency and not Geller himself

On your next pass time look at Geller vs. Freund on gold. Freund's class will likely already be full. Geller's will have 300 open seats. That says enough, doesn't it.

Bro loves Achieve, and while it's irritating, I learned more from Achieve than I did from him. You gotta teach yourself. He's passionate, but lectures are highly conceptual and fairly disorganized, with very few examples. Tests are all MCQ and mostly fair; you just have to practice. CLAS helped a lot, and so did the practice problems and exams

I was placed into his class because the other sections were full and was a little nervous due to the other rate my professor ratings. However! Geller is my favorite teacher at UCSB so far, even as someone who isn't fond of physics. You will succeed if you understand problems from HW, textbook, and assigned practice problems (not rote memory).

Not very good at teaching, but I was fine because I took physics in high school. The content is essentially the same as AP Physics 1. There's also a few homework assignments due every week and they're graded by accuracy. Start learning the content before the quarter starts and be prepared to teach yourself almost everything.

Conflicting feelings. Lectures are pretty useless, purely conceptual. Homework is a large percent of your grade, so failing is pretty impossible, but that's offset by the low test averages (71, 60, 57). These were his highest averages ever, according to him. You have homework due every day. Take Freud if you can't take a mild hit to your GPA.

He's is SO DISORGANIZED and BAD. He openly stated on the first day that his class wasn't meant to be a weeder course, but it definitely felt like one. He also mentioned that the department was unhappy with the discrepancy between his class and Freund's. His teaching made class impossible. He gives 3 question practice exams with no explanations. .
