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.

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.

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.

Of the entire Physics 6 series, 6C was by far the easiest. Nuclear physics was somewhat interesting.

class is SO easy. take him, easiest class i've ever taken in college!

Did a lot of demos and had clear lectures but has a tendency to give questions on tests that were not like the homework,lecture,or book (well for the final @least).He really makes u think.Physics is an interesting but complicated.He was a good professor, the best of all the physics prof i've had (3). He's pretty cute too, looks like a grad student

Way better than Fygenson. Very fair and good at explainging concepts. Tests are very fair. Easy to get a good grade with little studying.

Geller's 6A class is quite challenging, but with diligence and the right resources, you can succeed. The homework can be time-consuming, but using tools like unstuckstudy ai alongside the free textbook can really help. Attend lectures and stay engaged - the tests are difficult but manageable if you put in the work.

Exams are harder than they should be.

Geller is the harder of the two physics lecturers solely because he does not give students practice problems that directly correlate to the test like Freund. In addition, there is A LOT of homework which is the most challenging part, but overall if you understand the homework you will do good on the tests.

If you are not good at logic solving then probably not the best course to take. Thought professor was fine, just that the hw's did not scale properly so you would get hw that was really easy then it immediately became really difficult and you would not know how to solve it. Hws usually took a while so prepare for that.

If you haven't taken AP physics DO NOT TAKE GELLER.

Be ready to pay 60 USD to access the textbook and hw for a quarter. There are 3 online HW due dates per week and a mandatory in-class essay administered during sections each week. The exams are entirely MCQs so it is very easy to get thrown to B-. Lectures are fine but don't provide sufficient insight. Just take someone else's class...

Great professors, but the exams you need to take are harder than the assignments and harder to get a grade for.

This has been one of my favorite classes due to both material and professor. Geller is great and I loved the lectures. Tests were kind of hard, but weren't weighted very heavily (final = 20%). There is kind of a lot of homework, but it was generally pretty easy and didn't take long. Doing/understanding homework is necessary for good grade.

Only chance to ask questions is in lecture. He is responsive and helpful, but you're expected to rely on TAs for info outside of class. Lots of homework and reading per week. Lots of studying is recommended, you cannot just do the bare minimum in this class. Grading is dominated by your homework and quizzes but includes long midterms and finals.

Taking Geller for 6A was the most miserable experience I've had in any class so far. He is useless. You would expect for a math heavy class he'd run through problems in lecture, but he didn't do a SINGLE practice problem with numbers. Unsurprisingly, class average on the final was a 50%. Prepare to spend many hours teaching yourself the material.

In terms of difficulty, his class was not free, but I think if you put in the effort, you can get a decent grade. For his lectures, I attended every single one because they were so fun. He is clearly very passionate about what he teaches, and that passion is very contagious. I would suggest you do a quick review before the discussion sections.

Absolutely terrible! If you have to take physics and you're stuck with Geller, wait and take it with Freund. Geller has incredibly hard tests with problems that have never been seen in class before. He doesn't tech to his tests in lecture, and gets off by making exams incredibly hard. AVOID AT ALL COSTS!!!! HE'S THE WORST!!

This guy loves to use Achieve, which is the most stupid homework system I have ever used. His tests are easy and his lectures are always useless. Achieve is enough. The most time I spend on is Achieve. You just need to do the practice test he gave for his test, they are really easy.

The online version of Astro 1 is a blend of easy mathematics (Usually the hardest math being like AP Physics 1 level), really interesting concepts, and such. Expect to read a LOT for the online version of the class but it isn't hard at all. Great for a STEM elective, just okay for a STEM GE.

This professor is the worst one I have ever met, he has unlimited and extremely hard HW to do once a week, almost 6 achieve and very tough to have good grades. Never take his class, never ever take his class

Geller's astro 1 is the first course I took in this UCSB which is great!. His lectures are interesting and he's a nice person if u join his office hour. However, the reading is mandatory and quite tough for a freshman if u have little astro storage (but not me). There the homework is not friendly for people deficit in writing and carefulness.
