If you are not good at logic solving then probably not the best course to take. Thought professor was fine, just that the hw's did not scale properly so you would get hw that was really easy then it immediately became really difficult and you would not know how to solve it. Hws usually took a while so prepare for that.

If you haven't taken AP physics DO NOT TAKE GELLER.

Taking Geller for 6A was the most miserable experience I've had in any class so far. He is useless. You would expect for a math heavy class he'd run through problems in lecture, but he didn't do a SINGLE practice problem with numbers. Unsurprisingly, class average on the final was a 50%. Prepare to spend many hours teaching yourself the material.

Absolutely terrible! If you have to take physics and you're stuck with Geller, wait and take it with Freund. Geller has incredibly hard tests with problems that have never been seen in class before. He doesn't tech to his tests in lecture, and gets off by making exams incredibly hard. AVOID AT ALL COSTS!!!! HE'S THE WORST!!

This guy loves to use Achieve, which is the most stupid homework system I have ever used. His tests are easy and his lectures are always useless. Achieve is enough. The most time I spend on is Achieve. You just need to do the practice test he gave for his test, they are really easy.

This professor is the worst one I have ever met, he has unlimited and extremely hard HW to do once a week, almost 6 achieve and very tough to have good grades. Never take his class, never ever take his class

Not too hard but you should go to lectures. Homework is a bit difficult but often harder than the tests.

The homework is harder than lectures/tests. The exams are similar to lectures, so it would be wise to attend. If you took AP Physics 1 then this is very very easy, otherwise pay attention to mechanics.

Pros: I left his class knowing more about physics than I did with freund. HW is worth 40%, only one midterm and a final. Lots of in class demos Cons: Likely more effort than freund, and things you are expected to know for exams are less straightforward. More HW than freund, exams are a little harder, and less practice problems done in class.

Please take any professor over Geller. He provides no practices for the midterms or final, so you have no clue what you are getting into. Additionally, he assigns TONS of homework that benefits in no way, just soley busy work. Lectures are ok, however, he does not provide any practice for the extremely difficult exams.

He explains everything clearly and provides plenty of examples, so go to lecture!!! The tests are not super easy but fair, just do practice problems. The main con is that a few of the homework assignments were unreasonably long and there's a lot of them. Overall a good teacher who is passionate about the subject.

He is not as bad as people say. He really likes physics, and he loves explaining physics. If you do the homework you will get a B or A. Some weird quirks (do not email q's abt exams!!!!!) but you can tell he is a nice guy at heart. People pass off their lack of studying the material he provides as him teaching badly - physics just requires practice

He's a nice guy and his lectures are helpful, if a bit slow. There's lots of homework yes but most of it is helpful, and I found that if I was able to do the homework problems confidently, I'd do fine on the tests. His grading scale is really nice-- homework counts for a lot! I'd still recommend CLAS tho or relying on friends if you can.

Get ready to spend hours on homework that won't help you with the exams. With previous physics experience, the class will be a breeze, but the class is taught very poorly. He's nice and tries to make lectures fun, but honestly, the class is a major pain.Thankful for his grading scale though! Exams are multiple-choice and no partial credit is given.

I took Geller last quarter and I was essentially teaching myself the entire class. His lectures are not near enough of a help to get through the insane amount of homework he assigns so you have to cover most of the class's info on your own time. He makes the class more confusing than it needed to be because of his unorganized lecture style.

You can tell that Geller really tries to help his students understand physics in lectures. That being said, the resources he provides outside of class are not enough. Sign up for CLAS to get extra practice problems and do the Achieve since it's worth a lot. Our class did so bad that he made a 75% on the final a 100%, so there's hope for you.

This guy loves achieve, sometimes assignments almost every day of the week. Basically taught myself through the pre-lecture assignments.

He's the worst

Geller's lecture style manages to make concepts that are easy to understand in pre-lecture assignments much harder to grasp during lectures. From my experience, if you ask for help after class he's going to respond as if it's insane you aren't grasping the subject. You're essentially teaching yourself physics which is already hard enough as it is.

This man is a king. No exams or final this quarter just quizzes and homework. Although online, lectures are as interesting as they are helpful. Geller is not only an extremely capable lecturer, but is overall just a nice, cool guy who cares about his students' success. I could not recommend him more, the best professor I've had at UCSB.

He was fair most of the time! Midterm was very easy and always tries to cut down on material in order to save time and make the students' lives easier. His final was very hard unfortunately but just study a lot and you'll get well above average. Do the practice problems he posts and go to office hours. I wouldn't take him again but he was alright.

Unfair tester, totally screwed over the class with the final in 6B and 6C apparently. Just take Ernest Freund, he actually knows how to give a fair exam!

Great person, terrible professor. Just demos in his lecture, he even said that his "lectures are complimentary to the book". No amount of studying could prepare for the final, there were at least 8 questions on it that we've never seen before. It was purely to bring down the class average. Said there was going to be 30 questions but there were 38.

Nobody enjoyed this class at all. Long and boring lectures that are extremely off-topic. Barely any material is actually covered, only broad and off-topic discussions. Lots of "rambling" in a sense. Class was mostly empty. The final was extremely difficult and the average was very low compared to him praising 6C and saying how easy it was vs 6A & B
