Professor Geller seems like a cool guy, very knowledgeable on the class topics, but the class itself is very hard. Reading the textbook is a must, but it's overly complicated and hard to understand. Geller clears things up a little in his lectures, but even then things aren't explained very well. Overall, he's a cool guy, but the class is not fun.

Taking this class online, professor Geller posted all of his lectures day 1 of the quarter. This allowed us to work at our own pace and complete what we needed to on our own timeline. His instructions were clear and the workload of this class was very manageable. He is a good professor for life science students who need physics to be made easy.

Not sure how the class is taught/graded normally, but highly recommend taking while it's online! The class is basically set up so you can get an A if you just complete the online HW and do decently on the weekly lecture quizzes (no midterms or final). Geller seems super passionate about physics and gives many helpful real-life examples.

Wish Geller was teaching Phys 6B. He's a great professor and it seems like he's super passionate about Physics. He's clearly really intelligent and knows his stuff. He seems like a really nice guy. The class is structured so everyone gets an A basically.

Dr. Geller is amazing! I really enjoyed being in his lectures, he taught the subject very passionately, and definitely enjoys teaching it to students. He mainly steered it toward biology majors. There was a fair amount of homework and quizzes, however, the material was taught very clearly. I would definitely enjoy taking one of his classes again.

I hate physics but had to take this for my major, so I wasn't too hopeful about this class. The lectures are incredibly long (it's a physics class, so it's expected to be a bit intense), but they help a lot with the weekly quizzes. The homework isn't bad if you pay attention and can grasp the overall concepts/formulas from lecture.

Physics is hard, and pandemic learning is hard. But this guy is pretty fair in regards to grading. He put effort into making clear pre-recorded lectures, and you can tell he wants you to do well. Very homework heavy (Sapling) but I like those interactive homeworks personally. Id take him again.

Gellers covid syllabus is too good to pass up. If you're at all lost in physics he's the one to take bc not a single test. all hw on sapling(book) and some lecture quizzes. Super easy if fast math is not your forte. took other phys prof and honestly prefer geller. his grade curve is steep but makes sense bc it's basically an easy A with no tests.

For distance learning, this class was pretty unorganized. No set office hours, quizzes whenever he felt like it, no scheduled assignments until the week of. Make sure you check Sapling for due dates. They change without notice. Other classes I've taken have always had a set schedule in the syllabus, but not Geller's 6A. Quizzes are easy tho.

Sucked at teaching physics. Lectures only covered conceptual material, tests contained at max 1-2 conceptual problems. Final was really hard for 6B, like unreasonably hard. Had him for the entire physics series-- would not do again if I could

Geller is a really good lecturer, but you HAVE to go to lecture because he doesn't use slides. His classes were very conceptual and demo heavy (especially compared to Freund) so it can be tough to study with limited practice problems, but if you do sapling and go to lecture you should be fine. I thought his lectures were always really interesting

Terrible Lecturer. Grading was fair. From 1-10 in difficulty examples given in class are a 1 and test questions are a 10

took the 6 series with Geller. He's really into the topic and wants you to focus on applications. His tests were easier than Sapling. I would suggest going to lectures for the practice probs he did in class. Do the probs he posted on gauchospace.

Geller definitely made the class/tests a lot harder than it had to be. This is a level entry Physics class made for Non-Physics students, yet he would make the tests difficult enough to the point where the avg. score was always around a D. I walked away with a grade I was happy with but had to put in a lot of work, so it depends if youre up for it.

I got straight A's in Physics 6A and 6B, then ended up with a B- in Geller's physics 6C class. He's not a terrible lecturer, but doesn't do example problems in class, just explains concepts. Definitely wouldn't recommend for 6C if you have a choice. Prepare to spend time in the PSR trying to figure out everything he doesn't explain.

This is a professor has interesting lectures and demos. The exams may little bit harder than homework and in-class practice but i could promise that all contents are included in the lectures.

Professor Geller was a solid choice. He is very passionate about his subject matter, and makes the information very accessible in lectures. I would do readings, and just practice with new problems you haven't seen before. Heavy weight in the online homework, weights as much as the first midterm. The homework helps, and is basically free points.

Geller's lectures are absolutely terrible, but you kinda feel the need to go anyway. Out of an entire quarter (TR lectures), he had three day's worth of iClicker. Doesn't teach, just talks about applications and astronomy. Also, he sounds like Bentley from the Sly games. Big oof.

Geller is an average professor. He is really passionate about physics which is great, but his lectures are very conceptual, and he doesn't cover much of the 'practical' stuff. The final only covered the concepts that he discussed in class, so just do problems to familiarize yourself with the equations and you'll be fine.

Lecture is mostly conceptual stuff that wont be test material, but still go for the equations and problems that he wants you to know. Practice hard problems and go to CLAS. Read the book. No curve or very little curve.

The test is much different from his class material.

Geller is good lecturer. I respect the way he lectures. He knows what he's talking about and tries to elaborate as much as possible. However, he can get off track sometimes. He lectures, but he gives the vibe that he doesn't care about the the students which makes him lecture differently.

Unless you are naturally phenomenal at math and physics, avoid taking a class with Geller at all costs. Took 6A with him and got a C. Then took 6B with him and got a C-, which meant needing to go back and repeat it. Went to his office hours and was told that I'm "just not that good at physics, huh?" when I asked him a question. Rude+ condescending.

Professor Gellers lectures are pretty interesting and is pretty funny every once in awhile. The homework is worth a lot sake sure you do it and do it right. The midterms can be tough but as long as you practice problems you should be fine. Same goes for the final.
