Geller is not good. He genuinely does not care about the students, and prefers to be the more difficult teacher to gain a sort of bad connotation with his name, which he revels in. His tests are difficult, and those are the only things that make your grade. He did not curve either of the midterms we took, and both averages were below 65%. Careless.

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.

boring professor imo. idk why i took him

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

Funny, goofy guy, it really helps keep you entertained; he has a passion for the subject which really helps. Lots of demonstrations to conceptualize topics, sometimes homework is given before we actually learn it in class however this may be resolved in later courses.

You definitely have to read the textbook to get an understanding of the chapters. Geller provides the basics and connects them to biology, but nothing that was in the lectures was on the tests. The questions seem to get drastically tougher. The online homework is extremely annoying. I studied tremendously for the final and ended up with an A- on it

I took physics in highschool and found this class to be impossible. I used all my free time to study for this class and only got a C. He seems to be enthusiastic about the material but his teaching methods are hard to follow. He fails to give examples with actual numbers, leaving us confused on how to apply the equations/theories. TestsHARD

Having never taken physics before, this class was ridicuoulsy tough for me. I thought Geller's lectures were confusing and students would get easily lost, teaching us only the basics and not providing good enough examples to succeed on the tests. I studied a ridiculous amount only to end up with a B-, and that's with a generous curve!

Geller understands that people taking the physics 6 series are not physics majors and teaches accordingly. He tries to connect the lectures to biology and medicine concepts. Because it's physics its a difficult class but he grades fairly. His lectures can drag but it's very easy to ask questions in class and keep with the lecture. Uses iclicker.

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. 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 really is a great great great professor even though I did not get an A. I realized that when I'm taking Lubin's 6B. Geller gives you the definition, a lot of exercises and examples during lecture. They really helps.

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.

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.

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.

Professor Geller is awesome. The man is a genius and is a fantastic instructor. He is very reasonable when it comes to expectations of students, but he also loves to push them.

Just an average physics class. If you took physics in high school, you'll be okay with just doing the homework and practice problems. I didn't buy the textbook and I got by just fine. Geller has really interesting in-class demonstrations. He's a funny guy, but his teaching lacks clarity. He makes lots of mistakes in lecture too. (iClicker needed)

Professor Geller is great! He conducts his lectures at a steady pace, and he loves answering student questions. Attending lectures was necessary for comprehension, and CLAS helped a lot too, but overall class was fair. No surprises on tests.

Professor a fraud and un trustworthy beware
