Pablo's lectures are literally just him reading examples from the textbook word for word. That's all well and good for learning the basic concepts, but when the midterms and final ask you to apply them in ways you haven't been asked you before, you find yourself trying to teach yourself things in the middle of the test. I've heard his review sessions were helpful, but I had a class at the same time as them so I could never attend. The TAs were helpful, but having your homework be returned up to five weeks later meant we never really knew how we were doing on the concepts. His grading scale was very generous, which definitely helped me a lot, but I would definitely recommend a different teacher if you can.

I don't think I would take a class with him again for the sole reason that he did everything from the textbook. He would copy down exactly what the textbook had for each section and solve some of the much easier example questions. The homework questions would be based off the section exercises and were of a higher difficulty. The homework was also based off correctness but no answer scheme was given after so you could never really check whether it was right and what went wrong. All the exams were supposed to be multiple choice with no partial credit (not at all helpful for math). Three days before the final he changed it to open response but each question was still worth one point so partial credit really made no difference. Office hours were also relatively short and more or less reserved for clearing doubts on the homework. His review sessions were just him writing down the names of the topics on the board. Overall, it was not a well-managed class. However, the professor was accommodative in the sense that you could drop one or two midterms and he ended up dropping 3 homeworks as well. Considering that it was his first quarter here, I think he could improve but take him only if the other professors have much worse reviews.

In response to a previous comment, he doesn’t do any problems at all during review sessions. That person must have put their review under the wrong course. Actually, the review sessions were a really disappointing part of 31B with Pablo, because he essentially used the time to outline topics we would need to know on the exam (ex. Ration test. Root test. Taylor series; nothing we wouldn’t already know.) However, he is a really solid lecturer and someone I would definitely recommend. Our textbook is fantastic and he follows it almost exactly. I will say that he basically didn’t teach us Taylor series..l had to learn the entirety of that section on my own. Unfinished lectures were quite a problem for me personally. His grading scheme is generous, but our midterms were multiple choice, no partial-credit, 10 point exams (8 questions). The final was a 24-point partial credit exam- that’s how we should have been tested during midterms. I hope he sticks with that method for future students. Overall solid, and the other 31B profs have
horrible reviews. Go with Pablo!

Professor Sanchez was an engaging lecture, but if you had to skip lecture for health reasons or just personal reasons, you couldn't because none of his lectures were recorded. That means that if you were lost it was hard to catch up. Homework was graded on correctedness, which is fine, because he ended up dropping the homework, but it sucked because we never had answer keys and didn't get our homework back for quite a while. I wish that the class was more online friendly and that the grade scale was made more clear.

Pablo really gives tough problems to get you to think. All the questions for midterms and finals come from the textbook. The midterms were awful because they were just multiple choice, but because of a cheating scandal the final was made free response, which makes it much easier to at least get partial credit for your work. I would not recommend his class simply because of the exam structures, but I gain a deep understanding of the material.

Very tough class. Pablo is not a bad lecturer but he's not great, and he goes through material pretty quickly. For a simpler class he would be fine, but I struggled in this course material very much (even after taking calculus BC in high school). He is very generous with his grading systems, however. If you take this class, study a lot and make sure you go over and understand the 'difficult' sections of problems in the textbook.

Professor Pablo's lecture is relatively easy to follow because a lot of information are from the textbook. The exams are not tough since he already goes through similar questions in the review sessions.
In short, as long as you do your homework and listen to his lectures with attention, it will not be hard to get a good grade
