Fall 2023 - Professor Min was very organized in his class and provided Zoom sessions, class notes, and recordings to review after lectures. The homework load was very reasonable (one submission a week) and usually did not take up that much time. He said that he wanted to raise the overall average of the class after the first midterm and we had quite an easy midterm 2 and final. Just do the homework, study before the exams and you should be fine. I'm really glad that I had Professor Min for 31B!

Fall 2019 - Moreno was undeniably an excellent teacher. Very charismatic and clear with his lectures, he made learning the subject relatively easy. Though he does go fast sometimes in lecture, he has no problem explaining his work if you ask it of him. Homeworks were very light but very vital to learning the material and graded based on accuracy. As this is his first time teaching the class, he ended up making the midterms apparently too easy (with high means: 40/42 and 44/50) and overcompensated by making the final a pretty difficult 20 question multiple choice test. By making it a short mc test, he effectively "separated the A's and the B's in the class" which was his goal as stated in lecture, and sadly ended up happening to me (rip my 100% on the 1st midterm and A on the 2nd). Even though I ended with a grade I was unhappy with, I am so glad I had Moreno for 31B as I believe he made the class an infinite amount of times better and easier as it could have been. I can definitely say I have a hard time believing people who say 31B is a difficult course as he makes it seem easy.

I took Math 31B with Moschovakis in the Fall and although the class wasn't easy or anything, I thought he did a good job of teaching the material. It's true that he has an accent but you get used to it after a couple lectures. He basically writes down almost everything he says on the board so if you can't understand what he is saying, you can just read it off the board. Copy down the proofs but down pay attention to them, they don't come up on the exams. I only took Calc AB in high school and a lot of the people in 31B had already taken a lot of the subject matter in high school with Calc BC but the curve wasn't that bad. I got the average score on the first midterm (I was sick for like 3 lectures: really easy to fall behind!!!) but then got an A on his second midterm which pushed my entire midterm grade up to an A. His exams are super long and he gives you very little time. Both midterms were about 8 problems long but they all had at least 2 parts (some had 4) and it is incredibly difficult to do them in the time allotted. Same with his HW quizzes, which consist of 5 questions to do in 15 minutes!! If you don't know what you're doing, you're not gonna have time to figure it out during the quiz. Moschovakis is really approachable and will help you out if you need it. Go to his review sessions even if you don't have questions. Do the homework questions but do the odd numbers so you know you're doing them right. Go to his or your TA's office hours. Overall, I would recommend taking this professor if you are prepared to work for your grade. If not then take someone else.

Fall 2021 - With Pablo, the best way I can describe his teaching is with the parable of him giving us the fish instead of teaching us how to fish. He teaches directly from the book--whatever is said in the book is exactly what he writes on the chalkboard. He introduces us to theorems and then does really simple problems that don't teach us the strategies on how to actually go about solving the problems. I resulted to basically watching all of Professor Leonard online to make up for what I wasn't getting in class. Another major issue was not having recorded lectures--unless he was out for the day then he would record and even those were from the book completely. It was a genuine problem because there was lack of access/risk of spreading disease if someone had a cold which happened to be my case. Although his problems for his midterm/test are from the book completely, the difficulty came up in the fact that some things were just not known how to do. I did serious grinding the last week before finals to clutch up my grade to pass. One positive note is his very flexible grading strategy, basically giving you best case scenario on the grades you got for your midterms and your final--he will drop midterm grades if they don't result in your highest possible grade which is good. Overall, if you have the option to take another professor--who has good ratings obviously--you should take them not for a solid grade but for comprehension and understanding moving forward.
