Pablo is not bad as everyone says but I have to say that discussion and homework problems are tough and harsh on grading. His exams are all from practice exams he gives out so you only need to focus on solving them correctly and memeorize them all to get a satisfying grade.

I wrote a draft review that ended up being a short paper, so here is the very, very gist of the class:

1. Standard math class policies: homework and discussion assignments are worth some peanuts of your final grade, while the midterm and final make up most of it. The midterm can be dropped on a second grading scheme. Discussion assignments and homework are graded half on completion and half correctness. Discussion work is graded harshly by the TA, Kong.
2. The class is well organized: All lessons and chapters they will cover are shown from the start of the quarter on Ocal's github, which he uses in place of Bruinlearn. All discussion assignments and homework are there as well, in addition to helpful a practice midterm and final. Although I haven't taken the final quite yet, the midterm was fair and conducive to the practice midterm, and I suspect the final will be similar. (Fair=/= easy, again the class is quite difficult, but doable)
3. Ocal himself is a fairly nice person: Self explanatory. He delivers his lectures with excitement and tries his best to answer questions. Some things are a bit rigid like the fact that he still has assignments due the weeks where he has exams, which is annoying but manageable.
4. LECTURES ARE VERY VERY VERY CONFUSING: Lectures are basically a 1 to 1 of the associated textbook chapter. While the class has no proof based math courses as a prerequisite, it probably should. Off the bat, Ocal assumes you are comfortable with mathematical proofs, although, again, the course does not require any proof based math courses as a prereq. In addition, besides the proof part of the class, Ocal's lectures end up being extraordinarily hard to follow. It is almost as if the lectures are geared towards those who have already taken the class before. I went to all the lecture up until mid quarter, because the lectures would confuse me so much, so I ended up reading the book (which he anyways teaches out of) for the rest of the quarter, and it was actually less confusing than the lectures.

In essence, while the class is well organized consistently paced (albeit very difficult still), Ocal's lectures provide virtually no benefit to students taking the class, and honestly this could be a self study online class and would not be different in the slightest. If you are confident in learning the entire class by yourself, take it, the exams are fair and the work is consistent and available in advance. However, if you are not extremely comfortable with proof based math, then PLEASE take another professor.

Do not take this class with Pablo.

-He overly complicates everything. He made me confused about material I mastered in high school. He is very confusing often.

-I taught myself EVERYTHING in this class. If you have no their choice but to take him, you will NEED the textbook. It will be your best friend.

- Long homework that definitely helps to do well in tests as they are from the textbooks, BUT homework was crazy long often.

-Tests were tough. Exam 1 was hard. He is very unaccomodating to say the least. Exam 2 was harder and final was harder in my opinion. Seriously, if you can, leave 31b with another prof for the sake of your gpa and sanity. Take 33A, 33B 32A but leave 31B for another quarter with another professor, I'm serious. He will not meet ANY of your expectations,

-Good luck for this class. Youtube and Textbook help tremendously.

Do not take this class. For the love of Pythagoras and Euclid, DO NOT TAKE THIS CLASS.

If you care about math, your grades and your sanity, wait it out, take 31B next quarter, do 32A instead. He is the worst professor I've come across. I used to think humans contain multitudes, of yin and yang. But this guy is all yang.
1. He does not know how to teach, complicates and confuses the easiest topics.
2. His exams are hard. And he doesn't curve the grades. (the midterm 2 and final average was 70%, didn't curve it up)
3. Gives so much homework (30+ questions - and long ones) even during midterm and finals week. We had 2 huge homeworks due during finals week.
4. Extremely unhelpful and very unaccommodating. He has zero empathy, please do yourself a favour and don't take this class. And if you have no other option, I wish you the best of luck and pray that you come out alive.

I cannot stress enough to NOT take this man. Coming from Gannon (I LOVED HIM) for 31A, I came in with a solid understanding (took only calc ab in high school) of previous material. The VERY first day I knew I was in deep. He was only explaining exponential functions but the way he does is so beyond confusing I got totally lost. The only way you can succeed in this class is to a.) READ THE BOOK. He teaches from this, but worse. Secondly, teach yourself the content. For me, this came from "MyOrganicChemistryTutor" on YouTube. Homework is extremely lengthy and is ESSENTIAL to compare/work on with friends to succeed.

One thing I will say is his grading scheme was generous but MAN. This class took a piece of me. It took a part of my morale, a significant chunk of my mental health, and I thought it would take a piece of my GPA. Thankfully, not the latter but I was on the cusp.

All I can say is only take this class if you are prepared to pour in a TON of extra hours. Grind hard on textbook example problems and the ones at the end of the chapter. Also, there are true/false sections on the tests. For these YOU MUST READ THE TEXTBOOK and I'd always recommend going to class no matter how tempting it is to skip.
