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

Geller has my respect above most professors. He is very understanding. He cares about his students truly wants them to do well. However, that does not mean his class is easy it is sometimes not that interesting either I am not a fan of physics, nor am I very good at it.. But he made it so worth it and this was by far my favorite physics class.

I thoroughly enjoyed Geller as a professor. I think he was one of my favorite professors at UCSB. There were some very challenging concepts, but Geller had a way of making them seem simple enough for me to understand for the test. He was very generous to us this quarter regarding the events that occurred. Also, homework and iClicker help a lot.

Professor Geller is great! He's a very kind person and makes lectures interesting by focusing on more interesting topics and frequently using demonstrations. Super fortunate to have him for Physics.

Super helpful and understanding professor. He makes the lectures interesting. Homework and exams are fair. You can tell he cares about his students a lot.

Awesome professor and you only spend about 2 hours a week on the class.

Geller is one of the best professors I've had at ucsb. I hate physics but he makes it as clear as possible and his exams are fair.

Cool professor that really tries to do his best to engage his students in the material. If you pay attention and do the homework you'll do fine

Geller is a good professor but you will have to study for his tests. He provides plenty of demos to reinforce the general concepts of physics and as long as you can understand these principles, you should do well. The tests are difficult, but are manageable if you study both the book examples and the homework assignments, you should be fine.

There is no way to prepare for his midterm and final. The only reason why you need to go to lecture is for the iClicker because the rest of it is full of pointless demos. Do the mastering physics and understand it, and hopefully make some good guesses on the test and you will be okay. Just don't expect an A.

Geller is a nice person not a good teacher.I felt like I exhausted all my options with this class & still did not pass.I attended clas,did the homework & studied for the exams.The midterm and the final were very difficult,no way he prepares us for the exams.He does some cool demos but I mean I don't think I could've done anything else to do better.

He wastes his time on demos that don't even work. Class is useless, the textbook is useless because he gets the questions from the test out of NO WHERE. He expects you to just know everything, when he is inept at teaching crap. Don't take him unless you absolutely must. or if campagnari is your only other choice.LOL

Really interesting lectures but his tests are SUPER DIFFICULT. Homework is much more challenging than the lecture material and the tests are completely impossible. His advice is to do the book problems before the test so I would do everything and I still ended up with a bad grade. The class isn't really curved, there's just a grade bump to help..

while he may be a good physics lecturer he makes his tests extremely difficult. you can do all the homework and problems in the book but he throws a curve ball at you on the tests presenting you with problems that are 10 times more difficult than the ones in the book/hw.

Geller is the man. He does a great job teaching the physics series for bio majors - there is a good balance between conceptual and quantitative analysis. Finals are generally harder than midterms, but still very fair - if you know the material you will do well.

Geller is extremely helpful and clear. He strives to make certain that he is clear about what will be on the exams and gives a fair review before every test. It is very very important to go to class and take notes and later study the notes while doing homework. He is also very sociable and enjoys visits from students who are truthly interested.

Geller is awesome! You should definitely go to class if you want to do well in the class and you should make sure you understand the homework problems for the tests. I didn't do too well on the midterm but did well on the final to get an A. The curve is really helpful!

Even if you understand the homework, tests can still be difficult. He throws random problems that you've never seen before and assumes you can just figure them out based on what you've learned. Class is useless because the things he teaches really don't appear on the exams. I had better physics teachers in high school.

Geller is a great lecturer who can really engage people in the material. He understands that many of the students are not physics majors, so he does make concessions for them. Tests are not easy, but are fair, as long as you do the homework and understand it.

I liked him up until he gave us a ridiculous final...and only ONE midterm???? Give us a break! I will be taking a different professor next quarter
