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

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.

Professor Geller is a really passionate professor and has a love for physics, but the final exam was really frustrating. He had a full practice exam with none of the same topics as the real exam and didn't provide practice problems for the topics on the test. I studied a lot for the final but ended up putting an emphasis on the wrong things.

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.

Prof Geller is a good professor. A bit disorganized but cares about students. Tests were not organized well and it wasn't super clear what was going to be on the test. CLAS definitely helped

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

Geller is genuinely a horrible professor. Although you can tell he knows a lot about the topics and wants the students to be interested, his lectures are horrible. All he talks about is conceptual ideas when the exams were all math problems. Basically had to teach myself everything for the midterm and final. Do not take this class with him.

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.

He's great, class was terrible.

I see a lot of people giving rave reviews and then 3/5 stars. He deserves a 5/5 rating on rmp based on those people's comments and my personal experience. He was on top of any issues that arose technologically as well as responding surprisingly quickly to my emails when I had questions on class concepts. I enjoyed this class because he taught it.

He is an easygoing prof with understandable lectures. Pretty easy class with no exams, and HW was 75% of your grade (sadly homework deducts you if you get an answer wrong which is annoying), quizzes 25%. I would much rather have him for 6B than Freund. Oh well, I don't get a choice.

Took his class for Physics 6A &C. Such a empathetic professor and very understanding of his students especially in this pandemic. He drops your lowest quiz/ hw & curves hw. I like how the quizzes arent worth majority of your grade. I used to dislike physics but Geller def made me like it a lot more.

He's a solid choice. He's not gonna inspire in you a firey, lifelong passion for physics, but you probably have to take 6ABC for your major, so he fills that role quite functionally. He doesn't make things harder than they have to be, which is prob what you're looking for.
