Professor Rubin is the GOAT. For the first few weeks of class, he was experimenting with the class structure and used surveys for students to voice their opinions. To say the least, he took our responses into account and reduced the amount of worksheets per week and gave us more time for quizzes. He was a super accommodating professor! He had pre-lecture videos, which introduced us to the material and he elaborated on the concepts in class. Professor Rubin was friendly and open to questions in class and during office hours. He also has the best mugs. Overall, I would recommend him and I would definitely take another class with him.
The grade breakdown was:
Optional Homework (super helpful to do in preparation for quizzes/exams)
20% worksheets (based on completion)
20% Midterms (second one was harder than the first)
40% quizzes (takes 3 questions from the hw so you are guaranteed a 7/10)
Rubin is a great teacher, very clear, helpful, and understanding. I would very happily take a class with him again. He's great!
Lectures: Rubin is a pretty good lecturer, but the information itself is quite hard to understand. We deal with 3D regions, so it is hard for Rubin to draw at times. I don't think relying on the lectures will guarantee success.
Quizzes: There were weekly quizzes, and they were very reasonable. Most questions were directly based on the homework, so you're guaranteed at least a 3/5 if you look at the homework. He also drops your two lowest quizzes.
Homework: Homework was optional.
Exams: Because I took it during online classes the exams were open note, 24 hour exams. He made the exams in a way that google would not guarantee you a good grade, but as long as you can do the homework the exams are very reasonable.
Tips: Reading the textbook before each lecture will make understanding the material exponentially easier and will save you a ton of frustration. I recommend doing the homework, but if you don't want to, at least go through each problem and make sure you can do them.
Professor Rubin is an amazing lecturer and teacher. I will preface this by saying that I am not good at math. I've never naturally "gotten" it and it has ALWAYS been a subject I've struggled in, so the fact that I somehow managed to get an A should say something about how good this professor is.
Professor Rubin really made it possible for everyone to succeed and learn. I will be entirely honest; I was one of the very few students who didn't really understand what he was saying (I had no prior experience with 32A material AT ALL and I struggled with a lot of basic concepts), but that was on me, not him. He did such a great job outlining the topics and walking through them with his students. Quizzes, homework, tests were all very fair. He was clear with his expectations, followed through on his promises, and was very accommodating. He was super sweet and understanding too. Seriously, if you get the chance, pick Professor Rubin as your professor. He's awesome.
Professor Rubin is one of the most sympathetic professors I have encountered at UCLA so far. The material in this class is definitely challenging to learn, but Professor Rubin's explanations are fantastic. I recommend completing the reading in the textbook to supplement what you are learning in class. I also highly recommend going to office hours if you are struggling. Professor Rubin is extremely patient and kind, and he has a great sense of humor.
Professor Rubin was great, he was very good at explaining things and giving clear lectures. He did super well with the online format, and the recorded lectures were super useful to go back and reference. His exams were very reasonable, many professors made 24hr exams that honestly required the whole day, but his were reasonably possible to do in a timed class setting (although the second midterm and final were harder). There were some things where I felt like I never actually figured out how to solve problems until I did practice homework, the class time is less focused on examples and more on concepts. Overall, a very solid class, I definitely recommend.
The best professor! He's super considerate and caring of his students. During the first two weeks, he sent out multiple surveys asking how we felt about the class so far and really took into consideration our opinions, which led to him adjusting the workload and format of the class around what we felt most comfortable with. Also, his lectures are really clear and helpful. We had worksheets and quizzes every week to complete, but they really helped in the learning process and weren't too difficult at all, and his midterm and finals exams were very reasonable. The professor really influences my enjoyment of a class, so thanks to him, I loved this class so much.
Professor Rubin is great. He's a great lecturer and it is clear he really cares about the well being/success of his students. Highly recommend taking his class.
rubin is a really nice guy. he made sure to listen to students and made adjustments to the course as we went along. there was one worksheet a week that you work on during discussion. optional homeworks throughout the week too, and often they were the exact same as 3/5 problems on the weekly ccle quiz. midterms were difficult. we had 24 hours for them (two midterms) but i spend like 4-5 hours on it when it should've taken only an hour lol. spend like 8 hours on the final (also 24 hrs). this class material was difficult especially the beginning sections on planes and parametrization. lectures were recorded and uploaded so no need to attend. discussion attendance is not necessary too but helpful bc the worksheets are difficult sometimes. but overall rubin is rly nice.
Math 32A is not an easy course. But Professor Rubin made it a very pleasant experience. This class was online and Rubin did a great job answering students' questions and clarifying problems. His tests reflected the content in lecture and the homework problems very well. There were weekly quizzes which were sometimes hard and occasionally asked for concept reasoning rather than straight numerical answers, but if you did the homework a few of the problems were straight from the homework and were easy points. Homework was not due and only contained a couple problems of each concept from lecture, so it was pretty light overall. However, discussion worksheets were due for participation points, although you didn't need to attend discussion to do them. Both midterms and final were 24 hours.
Professor Rubin makes it clear that he cares for his students' well-being and understanding, and seemed very empathetic to our stress due to protests and Covid-19. I believed he ended up curving the class more than he normally would due to the circumstances. Best math professor I've had so far (out of 31A, 31B, 32A).
