Took this in HS so maybe I'm biased. Material's pretty simple, he doesn't seem to cover as much as other professors.

Class is interesting, class is cake if you have had AP physics in HS.

I love him

Very entertaining but you have to study on your own or visit your TA ALOT

Doesn't teach well at all relies on your own studying.

not clear at all

students get out way less parepared than those taught by other profs.

very clear, entertaining, didn't cover much

Einstien hair, hilarious, best physics teacher, funny, entertaining

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

His lectures are all conceptual and have nothing to do with calculations. After asking friends, I heard a majority of his questions are mathematical-based. In addition to his teaching, he also does not post any resources. His notes are from a student, not himself. And he does not provide any videos of himself explaining those mathematical problems.

Geller's 6A class is quite challenging, but with diligence and the right resources, you can succeed. The homework can be time-consuming, but using tools like unstuckstudy ai alongside the free textbook can really help. Attend lectures and stay engaged - the tests are difficult but manageable if you put in the work.

Exams are harder than they should be.

Geller is the harder of the two physics lecturers solely because he does not give students practice problems that directly correlate to the test like Freund. In addition, there is A LOT of homework which is the most challenging part, but overall if you understand the homework you will do good on the tests.

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.
