Y'all I'm going to be wildly honest.

1. I am not good at math (was openly the worst in my high school, luv that).
2. I did not attend lecture.
3. I did not attend discussion.

Oleg Gleizer is AMAZING. He's so nice, funny, and he's one of those professors where you can tell that he's truly passionate about what he's teaching. If you get the chance, I really recommend attending lecture. He often goes completely off topic, and I know that bothers some students.

However: he always remembers that this is a class, and it's unfair to constantly give us random tidbits and test us on different material. So, he often includes the fun little examples from lectures on his tests and quizzes.

Having barely ever attended lecture, and having never attended discussion, I was able to get close to 100 on all three exams just by looking at examples in his notes and in the textbook. I highly recommend taking this class with Gleizer, because his tests are so fair. Find the question on the test, look at his notes, look at the textbook, look at similar homework problems and find their solutions. You got this.

lowkey a glorified physics class

I think I would probably die in this class if it were in person but open book tests really helped out and were quite similar to problems he did during lectures, so if you're taking this in person I'd probably recommend really studying his lecture problems. He was a bit ranty at times and went on tangents but honestly as not a math major it was still pretty interesting. He's enganging and really kind and sweet and cared for his students- often moving hw and quizzes and stuff if people asked for it. Also, if you're a math major he's incredibly accomplished it seems so I would probably recommend going to his office hours.

Overall, lovely man with an incredible background. You'll need to put in some work but I think you'll enjoy the final product :)

~During Covid~

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.

As a non-math major (who really has disliked the lower-div math classes here), I'd say 32B with Gleizer is one of the much better experiences.

My conceptual understanding of Calc 3 is pretty limited so in that respect I wouldn't say Gleizer was that great, but if you want a good grade, Gleizer is the man - his exam questions are basically just past exam questions (which he gives to you) or textbook problems that sometimes were assigned as HW with the numbers changed. It's VERY easy to do well in this class, but his lectures are quite confusing at times especially towards the end of the quarter.

Grading scheme is: 30% Final, 30% Midterms (15% each), 25% HW, 15% Quizzes (5% each).

His quizzes test more conceptual topics and his exams are more computation based. He also does a lot of exam problems repeatedly throughout the quarter in lectures so make sure you pay attention. Overall, he's quite funny and laid back, but not sure how much will stick with me going forward.

Oleg is the best STEM professor I have had at UCLA. He is really funny and a really great lecturer, especially if you like math and physics. He loves to talk about how you should learn and think, and the beauty of mathematics, and how powerful math is to apply to the world. He is very often funny, and takes care to make sure students are following his lectures (but not in a way that slows the lecture down). He really just loves math so much, and we love him too. His tests (during covid) were long but fairly easy, and the homeworks were quite long as well. My only grievance is that he made it sound like there would be a pretty nice curve for the class, but the curve was only about 1/3 of a letter grade as far as I can tell. I'll miss him.

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!
