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.

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.

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
