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.

Prof Geller was very thorough with his lectures, you should go to lecture if you want to understand the material fully, along with reading all the chapters assigned. If you're interested in this topic, its not hard to pay attention and grasp the concepts, if you're not interested, its probably going to be rlly hard. Lots of hw too, but easy.

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.

I adored Geller's Astro 1 class. You can tell he loves teaching it. The class was thought-provoking and made me appreciate life more. If understanding the universe, stars, planets, and other celestial phenomena sounds boring to you don't take the class. His physics courses artificially lower his rating. Don't let that deter you from taking Astro 1!

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. .

NEVER TAKE PHYSICS WITH GELLER. Be prepared to spend the entire quarter teaching yourself and fail every midterm! Literally one of the worst professors i have ever had here at UCSB. His teaching is completely theoretical and does not relate to exams or homework what so ever. Incredibly hard tests. Final average was a 57%

Geller is so funny and his lectures are so interesting yet easy to understand. Homework is pretty simple. Lectures and hw correlate directly to exams so they're pretty easy. Since he wrote the textbook, his lectures basically follow the textbook so if you miss one it's not a big deal. Loved Geller and this class!

Take literally anything else. This was the most unpleasant experience I have ever had in a class. His lectures are entirely conceptual and completely unhelpful regarding homework or exams, which are entirely mathematical. Do not expect any practice exams longer than maybe three questions. Only take if you want to teach yourself the entire course.

Overall, there is a lot of pros and cons. Pros could be his midterms are all multiple choice and Cons is that his practice exams doesn't really help much it is not structured well. His explanations on it doesn't make sense. He should post an ACTUAL practice midterms or finals with good explanation that way students can learn from him better.
