This is by far the worst class I have taken so far. The lectures are unclear, and it seems like he doesn't understand the content when teaching. He is not confident when teaching this class and often messes up the answers, making it quite confusing when learning. I'm not saying he can't make mistakes, everyone does...but when it happens for every single problem or step, especially with signs it makes it very confusing when learning the content. The homeworks are so long ranging from 20 to over 30 problems a week. His review sessions for this class for the exams were also not helpful. He put problems on the board and then expected us to complete them. He does have 3 grading schemes which were nice, however, he does not prepare you at all for any of them. My TA taught me more content than he did. I ended up having to use the internet for studying everything since his notes and lectures are not helpful. The way he words his sentences are unclear and it is hard to comprehend what he is trying to say to the class. Do not take this class with Ocal if you can avoid it at all costs. The content is challenging so having a professor who knows the content would be nice.

Worst professor I've had so far. Pray you don't have him, or your grade will suffer, even if you know the content. Literally assigns an insane amount of homework, and tests are needlessly impossible. Also doesn't understand the idea of a curve. He tried to curve only one class's grade and not the other's, and really thought that was a good idea, so he just made the curve less and destroyed everyone's life.

DO NOT IGNORE THE REVIEWS ON HERE!!! This class was so tough. I went to every lecture and just about every ta office hour (his are not helpful), but I still heavily struggled. I felt like I was given very elementary calculus skills in lecture, then handed difficult and long-winded homework problems. I required help for many of the homework questions and my ta Zerrin was super helpful. The midterms and final were no different. There was a whole issue with the first midterm, as he curved one of his classes but not the other??? The class average was around 75 for the first and 60 for the second one and only the first was curved. The final was also very hard and realistically the average will also be probably a 60-70. Again, no curve. This class was not at all helpful for my calculus skills. Avoid Pablo if you can.

If you need the textbook I'll give it to you for $5 text me **********

Pablo is the worst teacher I have ever had. He has no clue what he is talking about during class and cannot describe an integral for the life of him. He constantly makes mistakes, confuses everyone, and just seems like he does not know what he is teaching. NEVER take this class if he is the teacher. Honestly I’m going to stop going to lectures because they are the most unhelpful, confusing aspects to this whole course. I truly do not know how or why he was hired.

This is a professor who spends only half of his class time teaching because the other half is spent on apologizing for his error. Basically, for every two lines he writes on the board, one of them would be wrong. Students have to point it out for him. He effectively makes this class more challenging than it's supposed to be because I have to identify which things he teaches are correct and which are not.
Also, no recording, so you have to attend the 9 am class. It's only the fact that he dresses so badly that convinces me the school isn't keeping his job for his looks or sth. School's just stupid in selecting its professor.

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!

here is everything you need to know about this class. i took this class winter 2023 as a freshman (similar to many of the poor reviews). 1. homework is helpful. he uses the EXACT SAME questions on the final and midterm!! or exact same question with different numbers. 2. maybe ppl talked about the difficultly of understanding prof pablo. i don’t think that’s the issue. if you are on your phone in class, playing chess, watching movies, etc, of course you won’t be able to pay attention. he will pause the moment someone raises their hand and answer their question until he makes sure that they understand. you get out what you put in. simply stated, IF you care about this class and are willing to put in focused work, you will be fine. yes, he closely follows a textbook (it is a free pdf he provides btw). but, the positive of this is that you know EXACTLY what he will cover each class before he covers it; no surprises. a good study hack is to study what he will teach BEFORE HAND ! 3. HOMEWORK ADDS UP!! do your homework it’s worth a large portion of your grade! it’s difficult to do but i did them all in my discussions and it is very doable. 4. he is the sweetest guy. seriously. and the TAs are great. they are just genuine ppl who want to be there to help you. this class is so hard, at any high-level university (it’s UCLA—of course it’ll be harder than any Calc BC class you took in high school). but pablo is a caring guy, and he truly takes into account what feedback we put onto the feedback form. his lectures got a bit better after our first feedback form, and even better after our second feedback form. with a good amount of effort, most people do fine in this class. yes, it’s not an easy A, but it is a doable A or B.

Pablo is a super nice guy and funny, his teaching wasn't the greatest, but I definitely saw improvement throughout the quarter and I know he wants to do better. His midterms and final required lots of memorizing, but weren't bad. He gives a ton of partial credit too. Overall, Khanacademy is your best friend, with Pablo being a funny guy to also help.

Avoid this class if u can this man doesn't care at all about his students. Tests were very difficult and he refused to curve out midterm despite having a 60% average because he didn't feel like it.
