Geller is a true gem. He really cares about his students and his passion shines through. Straightforward exams if you like physics.

Final harder than the midterm. Lectures are mostly applications, but the few problems he does are helpful for the exams. CLAS is useful. Practice doing hard problems to be ready.

He goes over more conceptual and application stuff in class, so some people didn't like that he doesn't really go over solving equations in class. The midterms and finals are based on the homework, so definitely study homework problem and you'll be fine. Also recommend going to CLAS.

You will have to do a lot of studying on your own just to pass the class. I Recommend taking any other professor. Never once did a practice problem in class with number figures(like they are on the tests).

I wanna attend any of his classes again. Each lecture he introduced only include a small part of chapter in the book. Sometimes when he had a cold he just skip the lecture and leave us to learn by ourselves. He always assign a lot of homework with tough and strange requirements. And what his lecture did little contribution and help for homework.

Geller is a great lecturer and person, but he also doesn't cover everything that you need to know in lecture. Reading the book, doing the homework, and going to CLAS will supplement his lectures in order to be prepared for tests. He only has two homework assignments a week. I really liked his class, but the set curve makes it difficult to get an A.

I dislike physics but Geller was such a good teacher. He doesn't try to trick you. I strongly recommend doing book problems because they really help you prepare for the midterm and final.

Took Geller for Phys6ABC because he's an amazing professor. Grading criteria is straightforward and almost everyone gets at least a B (75-89%) in the class. The tests will determine your grade in the class and there's only 2 or 3 so be well prepared. Vince Zacone's CLAS online material is your best friend. Geller is an awesome person, you willlearn

After taking Freund for 6C, I found Geller's class to be more challenging - I had to put more effort into studying and actually knowing the material, rather than memorizing equations. However, Geller's passion for physics and science in general made the class interesting, and I didn't mind going to lecture. Don't forget to bring your i-clicker!

Geller was alright but kinda boring sometimes. He really cares about his students.

Best physics teacher I've ever had. He doesn't do flipped classroom like other teachers which is helpful and takes tons of questions and does a ton of examples to make sure you understand. He is really funny. Tests are very fair compared to other teachers-doesn't trick you and tells you how many questions of what topic will be on there. One midterm

Most of the (many) issues I had with the course are due to the poor curriculum, which is set by the department and not the professor. However, Geller was often smug, condescending, and discouraged us from going to office hours for homework help. PHYS 1 is easy if you have taken AP Physics. If not, prepare for a long slog with little/no support.

Halfway through the quarter, and personally I dislike his teaching style. Lectures are pointless, only reason to go is because of iClicker points but otherwise you do not learn much through his lectures. The class is self-taught and he only provides demonstrations of the main concepts rather than actually going over what will be on tests.

Geller is the best professor to take for the Physics 6 series. I've had Dr. B and Lubin before, yet Geller had the most clear-cut expectations for success on tests out of all those professors. Study Sapling, go to CLAS, and briefly go over the lecture notes for any practice problems he does during class. If you put in the work, you will be okay.

Geller is the best professor hands down!! So fun and highly encourages class participation and questions. Lectures were interesting and he always had demos to keep it fun. Definitely recommend this class as an Area C requirement

Geller is a chill homie. He is super cool and loves questions. You will leave the class wanting to take another one of his classes.

Geller. Hmm. What should I say besides that he's an amazing human being? I got a 64% on my first midterm. Worked hard, got 100% on the final and barely met the range for a B+. He BOOSTED me to an A! Geller believes in hard work, and he rewards his students accordingly. Take over any other physics professor!

Geller's a downright awful lecturer, but at least he shows enthusiasm for it. He focuses too much on applications and not enough on the theoretical aspects of physics. That being said, do the book problems and use lecture as a test to make sure you're on track, not very useful otherwise. Could've had potential, but interesting topics nonetheless

Prof Geller is a great teacher. He lectures on exactly whats going to be on the test. His tests are basically the Sapling assignments so be sure to go through them before each test. I got an A just by going to lecture and review notes and Sapling the day before the test.

Geller is eager to answer questions during lecture, and although there is assigned reading, the lectures cover most of the material so the textbook is only necessary for some terms or concept that you don't understand, and the homework. The class was pretty interesting

Just as Professor Geller said from day one, this class had a good ratio of easy and interesting. Super cool class, great professor! Highly recommend.

Robert Geller is a solid teacher. His lectures are not too boring and he encourages questions. If you pay attention and take notes you can do well. I felt like I really learned the material in the class.

Geller's like your cool traditional Isla Vista teacher from the 90's. He teaches you the basic 6C concepts using compelling demos that will stimulate the Gaucho mind (e.g. the hallucinogenic appearance of soap) albeit still using overhead projectors. He's funny, his teaching emanates passion in his teaching, but watch out, his tests can get you!

He is an interested and goo-natured professor. He is supportive of all students and he will reassure students that are struggling. I really appreciated that because I am not the best at physics. He had iClicker a few times and his tests were very similar to the Sapling assignments.
