While the other reviews are indeed correct that his class is quite a bit of work, as he does assign around 20 questions per homework, which often takes a few hours, the truth is a 4 unit class expects around 4 hours of work a week, and there are only 5-6 homeworks, thus spaced out over 10 days, so it is not to demanding...His problems are chosen wisely to help you get an intuitive learning of the process, and understand the material. His tests are fine, the first two were take home(and collaboration was allowed, the second midterm was much harder than the first as we averaged 100% and we definatly needed the collaboration), since we were moving to slow in our class, and we did not have time in class, the averages were around 100% on both midterms

the final was a diffrent beast though, the average was a 52%... There was obviously no collaboration, one 3x5 note card, and despite what other reviews said the test was not harder than his 2nd midterm, there just was no collaboration.

20% of the grade was from homework(lowest dropped), 30% over the two midterms(15% each, unless the final was better than a midterm, than it's dropped, and the final is 65% of the grade), and the final is 50% of the grade.
My best advice for his tests, when he says a question from class will be in the midterm(he loves vortex fields, torus strips, cones and all their many miracles, 4d spheres, integral of a gaussian curve, and maybe proving some theorem given in class ), look up how it's done, and put it on your cheat sheet(a 3x5 sheet). Your cheat sheet will best serve you, if it's more tailored to questions, rather then a bunch of formulas. This certainly saved me in the final for the class. The formulas are quite intuitive, but write down the questions(gaussian, torus, cone's center of mass, etc), and then you'll do fine on the tests! Overall hard class, but he is more then willing to answer your questions in class, more then willing to derive stuff in office hours, and more then willing to help. I would definatly take this class again with him, and definatly take another class with him in the future. It is quite a bit of work, but then again if you want to understand a topic well that takes a lot of work.

Honestly if you don't have to take this class then don't. Assigns heavy homework and is very bad with spacing out the homework and expects you to complete 20 problems (which doesn't seem like a lot but with 32b math, it is) over like a week timeline(that is a requested timeline like he was going to give us like five days to do homework) or will give you just six days. Also he assigned homework on the Wednesday before thanksgiving break to be turned in person on paper (even though students are going to be traveling). Like keep in mind if you're taking other classes this is such a large workload to get done in that amount of time. His lectures are so unhelpful or not clear so you just have to end up reading the book. Will call you out if you disrupt the class (like this girl tripped one time and he called her out in the middle of class for being disruptive and called out another student for using their phone but the student was translating the lecture from English to their spoken language -it was so bad) honestly not a good class, don't take it. The only good part of this class was that he was sometimes funny and in general everyone is also struggling.

Honestly Gleizer is a nice person, but I feel like he's a below average professor. I tried hard in this class and studied the textbook and sample midterms/finals, but its just a waste of time. His tests are basically if you're good at visualising, you'll know how to do it, and if you don't you'll fail the exams. Homework every 2 weeks is basically 20 questions out of textbook, and extra credit is only given if you answer the super hard bonus question on his midterms and finals. The mean of each exam is basically 60%, and he grades on a straight scale so no curving. He's not a good professor at explaining concepts, and I attended office hours but he still fails to explain the rationale behind the integrals we do. Do NOT choose him if you have an alternate choice.

The reviews from 2020 made me think Gleiser would be a fair professor. As some of the other reviews said he basically failed half the class just because everyone did good on the midterm. Lectures after week 6 were impossible to follow as someone who got B's in 32A, and 31B so take from that what you will. Currently taking 32B again with another professor and the grass truly is greener on the other side, do not take this class with this prof learn from my mistake.

Overall, Professor Gleizer's class was pretty good. His lectures were alright - they were super detailed but he was a little unclear at times. The exams were of medium difficulty. Some of the problems were easy, while some of the problems were pretty hard. However, he is pretty lenient with the grading. Since our TA was absent for much of the quarter due to personal reasons, he boosted everyone's overall grades by 8%.

Prof Gleizer is one of the most helpful professors I've ever had. Even though he can be kinda confusing at times, it is clear that he really cares about his students. Go to his office hours! He is super super helpful and nice, and they really helped me understand the course material. His tests are also fairly straightforward as long as you make sure you fully understand the in-class examples and homework problems. Also do the practice exams! He's a really amusing guy, and I'm going to miss his class.

Generally, I had a pretty good experience with Gleizer. Gleizer is super sweet and it is obvious that he has a passion for math and he genuinely wants to help us students understand the content. Tests were pretty fair. They were usually problems similar to ones that we have gone over in class. Homework was a little heavy at 20 problems a HW assignment (at least compared to other math classes I've taken) but there was only 6 HW assignments for the entire quarter. Lectures started out fine but it eventually became gradually more confusing as the course went on (the content gets progressively more difficult). But all and all, I enjoyed taking this class with Gleizer!

Gleizer is an amazing teacher. If you go to lecture and pay attention, that is all you need. His tests are often based on examples he goes over in lectures, so look over his notes before exams! It would be better if you have taken Physics up to 1B, as he has a number of physics examples, but it is not required. Overall, this class is very, very good. Take him!

Best prof ever.

He may come off as stern in lecture and it can be hard to understand him with his accent sometimes, but he is actually insanely friendly and dedicated to making sure you understand the material. Take this class with him. His homework is not too demanding, and it prepares you well for exams. Additionally, you need to at least read his lecture notes if not attending lecture because many of his exam questions are directly covered there. Exams are straightforward and don't test you on anything not covered. Very doable if you've studied. Not exactly easy, but I think that's just the material of the class, too.

GO TO OFFICE HOURS. He's so helpful and friendly there, really makes the class a blast.

I like Oleg. He has his faults - he's prone to rambling during lectures, sometimes goes over stuff that is poorly covered with the textbook, and has this strange resentment with north campus-like majors - but he's a good math professor.

He goes into great detail regarding topics and theorems, and often gives real world examples for those who are less theoretically inclined. Each of lectures has at least one example per topic, sometimes more, and he really delights in answering questions, so ask as many as you need. Lastly, and perhaps the only one I have seen do it so far, he holds office hours during all times of the week, for those who are local and those who are overseas, so that all of his students can make office hours if need be.

Testing wise, he will, and I mean this, he will absolutely tell you what will be on the exam. He will tell you, like, that you will have to parameterize a torus and then will be willing to do it in office hours, if you ask him a week later or something.
