It's pretty clear that the professor tries hard in class, but class material just does not make any sense to me. Professor's spanish, so maybe that's my fault not understanding his accent, but I could not learn anything in class. Fortunately, I got a pretty good TA and he basically went through all the class material in 50min. Professor never relies email as well. My friend went to him after the exam (the only time that we saw him in person) and he said he did not have time for us and he would reply our email, but he never did. My midterm was a B and a C, but did not know why I got a A- for my final grade. Final exam results were not disclosed, and it was super hard. I have literally done every practice questions in the textbook and still saw questions that I have never heard of in the exam. The final grade was good, but his class is nevertheless not worth it.

Was super nice due to the fact that it was the first quarter back from covid. Tests were harder than homework. He was alright at explaining the material. However, would always go overtime and rush to explain his last example. The last few minutes were super confusing.

Dr. Madrid is very friendly, helpful, and generous with the office hours! The class is very hard, but if we attend the discussion and office hours regularly it helps a lot! Our TA Steven Truong is awesome as well. I suggest everyone who take 131B to go to Steven's website and review 131B materials since test-related concepts are on there. Tests are all online, hard, and require some creativity. There are 2 midterms (24h) and 1 Final (48h). Overall, Dr. Madrid makes this class a lot more tolerable!!

Madrid is the best professor I've ever taken, probably my favorite. He is really engaging and funny and occasionally roasts people during class. he is realllllly nice and laidback. You can tell he really cares about his students' learning and is very passionate about teaching. He's also really helpful and patient during office hours and makes sure that students fully understand everything there is to know. His midterms are slightly harder than the homework but I've heard he curves generously. Overall 10/10 I would take him again.

in fairness he was actually a really nice guy, but a hot mess of a prof. DO NOT TAKE; material is way too hard for a calc 2 class and the exams (especially final) included shit he did not cover in lecture. Wouldnt even release the final exams to see where mistakes were made; unresponsive to emails; overall not a good lecturer

The best math professor I have had in college. He always seems to be enjoying himself, is very personable, and makes classes an enjoyable experience, all while teaching the material well.

Young and passionate professor, cool accents, often funny. Sometimes disorganised, but everything he explains during his lectures make sense. Also gives some kind of 'extra credit' by making the final out of 115, but the total points you can get from the final is higher so you can theoretically end up with something like 104% (will be treated like 100%). Overall recommend him.

A very fun guy. He's always laughing in class, so lectures aren't boring. His accent and his ability to explain math make the learning part a little bit hard, but it's definitely manageable. The first midterm took me by surprise, but he definitely explained the format of the second midterm and the final well.

Madrid is awesome. The dude is pretty funny. He is like 25 years old and has a sick accent. He really wants to help his students understand the material. His tests are not the easiest but he shoots for about a 65% average and will curve if necessary. He is always available to help, I even scheduled personal office hours multiple times and he immediately got back to me and eventually helped me with my question. His lectures are solid, but make sure to read the theorem proofs from the book too. He gets a ton of his test questions from the book so just be sure to do extra problems from the book. Overall, he made Analysis my favorite class at UCLA. I highly recommend!

Also, he makes it clear that as long as you put in a good amount of effort, he will pass you. He does not want to fail anyone, but just don't take advantage of his niceness. He deserves your best effort.

Professor Padilla is a very nice professor. It is already Spring 2019 now, but I have to write a review for him because he is probably the best professor I have ever seen for my first year in university. His lecture was incredibly clear, moreover, his slides were very organized. His lectures sometimes get really funny, and he could make super complex theorem easy by giving very ingenious intuition. Definitely recommended.
