Fair class, we were given cheat sheets and calculators for tests. Can have somewhat hard test but gives u a syllabus of whats going to be on it. Fun demos, good personality and funny. The only downside is that too many fun demos less teaching. Needs to teach the material more and not go off on astronomy tangents. Over good prof. with a curve.

Never had any prior classes in physics. Didn't do very well on the midterms, but with the curve I ended up with a B-. Get help from CLAS and use his office hours. Do well on HW because that's worth equally as a midterm. Does very fun and cool demos in class and class is rarely boring, except the lecture on Astrology.

There is no way to prepare for his midterm and final. The only reason why you need to go to lecture is for the iClicker because the rest of it is full of pointless demos.

Geller is a good professor but you will have to study for his tests. He provides plenty of demos to reinforce the general concepts of physics and as long as you can understand these principles, you should do well. The tests are difficult, but are manageable if you study both the book examples and the homework assignments, you should be fine.

Professor Geller is a great professor. He is so willing to answer questions that he would often stop lecture just so we could ask questions.

Dr. Geller is amazing! I really enjoyed being in his lectures, he taught the subject very passionately, and definitely enjoys teaching it to students. He mainly steered it toward biology majors. There was a fair amount of homework and quizzes, however, the material was taught very clearly. I would definitely enjoy taking one of his classes again.

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. .

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!

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.

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.

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).

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

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.

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.

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

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.

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.

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 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.

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.

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.

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)

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

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.

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!
