Super light workload, easy tests, lectures were informative + engaging and posted online. Knows his material.

Very difficult class to follow. Often walked away from class feeling like I understood very little from the way the material was taught. Like others have said, it is clear that professor Ocal knows the material well, and is knowledgeable. However, his method of teaching is unsatisfactory for many, as it is very unengaging, passive, and extremely fast-paced. He repeats much stuff directly from the textbook, without really dissecting the concepts themselves. The best way to explain his teaching is that he teaches it as if he assumes the students will understand what he says immediately after he says it. Definitely do some practice from the textbook, look up these topics from more engaging instructors on youtube (ochem tutor and bprp!), and manifest with all your might.
The TA I had, Kiran, was also extremely confusing in his explanations, and often further complicated the lecture material for me. Worked really fast/brushed by concepts quickly, did not engage with the students while explaining, and would often make mistakes WHILE explaining. All of these factors made for a very difficult class, and I would not recommend it for 31B.

If you even remotely enjoy doing math, spare yourself the pain and avoid this man at all cost. Where do I even begin with Pablo? This professor is the worst math professor I've ever had and that comes from someone who has an abusive math teacher in middle school. He is sooo unhelpful, uncaring, and overall bad at teaching. He either cancelled class or recorded videos for the class several times because he could not make it, but when it came to me as a student being unable to send out a homework on time he always said he can't since he has 700 hundred srudents and that it's against policy. My overall feeling towards this class is that he truly did not care for students and as someone considering to do a minor in math/statistics, after taking his class I would not want to do another math class even if I had gun pointing to my head.
