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

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.

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.

I adore Geller! there are a lot of topics to cover but he tries to trim down as much material as he can. The final is a heavy portion of the grade and hard. But the midterms are usually easier as he gives practice midterms. Homework problems don't help/aren't on exams but saves your grade as its are worth as much as the final.

The physics is tough, but Geller shows true interest in his field is fair with the curve. I personally thought the tests were hard but the online Achieve homework is CLUTCH when it comes to grading. It is a good proportion of our total grade and makes up for the -in my opinion- hard tests. Only issue is that lectures are broad compared to Hw.

Honestly, Geller has been one of my favorite teachers so far. Overall he is a super cool teacher and I don't find his physics series to be extremely difficult. As long as you stay on top of the achieve homework you will do well. Plus, his lectures have been pretty enjoyable, despite being at 8am.

So this is a hybrid class because covid messed everything up. His lectures are terrible. Conceptual examples, no further examples or questions. You have to teach yourself. The homework is heavy but it helps with practice. Fingers crossed I pass this class, but the person teaching me this material is myself.

He gives extremely easy conceptual based questions in class during lectures, the hw is hard and there are at least 5 things due every week, then comes the tests covering only math problems that he never taught in class That we have to teach ourselves !! We frustrating class felt prepared for exams and it was never enough

At first I wasn't sure what to think of Prof. Geller - His lectures were super fast paced and at times a bit disorganized, but over the 10 weeks of the course, I developed a lot of respect for him, and came to actually really enjoy his lectures. It's definitely a tough class, I won't lie, but he is encouraging and supportive with his students

this is a horrible professor just because his final exam is so difficult. The average score of the final exam just 57%, but this is just an introductory Course of physic. I am studying economic, I choose this course just want to satisfy my ge requirement. so, I cannot understand why he make this introductory course final so difficult.
