I had Pablo for Math 31B, which I confess was a difficult course with him. However, since I took him the last time, I'm not sure if it's because he prefers linear algebra over calculus or if he's absorbed all of the reviews he's gotten, but man has he improved significantly. I can now confirm that he is in fact a brilliant professor!
Every homework (and exam) problem was manageable and accurately represented what he lectured on. He did not assign any tedious homework and, in fact, made part of it optional through ”recommended exercises.” Not to mention that some of our exam problems were similar, if not identical, to those from homework and discussion.
He is not out to trick you or anything. He’s easily accessible and if you need help, don’t be afraid to go to OH! He’s super friendly. Thanks for a great quarter Pablo!

In terms of teaching, probably the worst professor I've ever had. Lectures were extremely confusing and it seemed that he relied wayyy too much on the textbook because he would read almost word for word from the textbook. It didn't help that the textbook was also not very good. Put simply, he didn't do a very good job with explaining the concepts and it eventually got to a point a few weeks in where I just couldn't watch his lectures. The only reason I did well was that he copied his test questions from the textbook, so as long as you knew how to do the textbook problems, you were fine (he gives you a link to the textbook, no need to buy it). As for the class itself, I can't really say how much I liked it because of how bad Ocal did of teaching it, but if you need to take this class, do not take this professor unless you can teach the concepts yourself in which case you will do well on tests since he copies problems from the textbook.

What a horrible dreadful man. Don’t trust him. Pablo if you’re reading this, I know what you did.

Don't take a class with this professor, period.

Lectures were straight forward and notation was generally similar to that of the textbook. Your homework problems will be from the textbook as well, and exam problems look pretty similar to homework. There are some multiple choice problems and true/false that account for about 25% of your exam, and the remaining 75% is usually free response (so you can get partial credit). The grading scheme is pretty standard, you can drop your lowest midterm (there are two midterms total). You definitely need the textbook for this class, so get it early on in the quarter or before it starts.
