Just saw that Jose is teaching 32A again so I'm leaving this review. While it has been a year since I took this class, I can still say that he is the best math professor I've ever had. Take his class if you can.

Great professor and someone you should take for a class like this. While homeworks could be a bit tricky, he offers to solve them in office hours. Notes do go by the book, but he usually provides alternative proofs to various theorems which helps with understanding. Exams were fair and he never tried to trick you. They were based off of in class examples and homework problems. I wish he were teaching 131B because he did a great teaching this course.

The GOAT

Yanez is one of the best professors I've ever had. He's clear, posts the notes online, and is always willing to give a helping hand. He's even willing to help and support people, not just in his lecture, which just speaks to his overall generosity and love for the subject. This was my first math class at UCLA, and I couldn't be more grateful for this fantastic professor.

Professor Yanez is a very passionate and efficient instructor! He is always positive and tries his best to help all students. He is very organized, as he consistently posts the lecture recordings, notes before and after lecture, and suggested problems. For Math32A I highly recommend you keep up and do the suggested problems the day of or the day after lecture! It's a lot to go over all of them right before midterms. Go to office hours, he's very helpful and will walk through difficult problems with you!
Midterms are very reasonable; keep in mind there aren't that many questions (as the test is only 50 minutes long) and the professor isn't evil and won't put a completely weird question in there.

Prof.Yanez is an engaging, clear-minded professor. He gives pretty structured lectures along with detailed lecture notes that are ready for us to fill out during lectures. After every lecture, he gives out a sheet of suggested problems and picks two as homework problems. Sometimes those problems can be somewhat tricky, but he offers to solve them during office hours. For the exams, although there is no practice exam, he pretty much follows the examples he gives on the lecture notes and homework problems as well as discussion problems. You'll be fine as long as you understand the logic behind some of the key concepts and the necessary tricks needed to play around with them (he also offers tons of explanation of the tricks during OH). Granted, real analysis is considered to be one of the hardest topics in undergraduate math and 131A as one of the most challenging upper-div classes. Yet in general, I think he makes real analysis more approachable than I thought it would be, and his teachings underpin a key component of our learning of mathematics, which becomes a milestone to embark on for the rest of the journey.

absolutely loved this class, yanez is so friendly, helpful, and such a clear lecturer. tests were fair, work is manageable. i recommend doing all the practice problems he assigns as they really helped me ground the material and develop a better understanding of what we were doing, especially if you're in a math or math related major/ if you're taking 32b. there are a lot of resources, as the textbook is great imo. 32a is generally not a course you can cruise through and you definitely need to put in the work due to the course content, but yanez makes it fair and as easy as possible given what you need to learn. made me remember why i love math.

Loved this class and professor. Was scared to take multivariable but Yanez made it manageable, and would remind us to breathe before tests. He clearly cared, and I felt the midterms and final were fair. Highly recommend.

Yanez is the goat. Absolutely loved him as my first math teacher at UCLA. His class is manageable, the tests are tough, but fair. The homework is helpful and he is easy to understand. If you are struggling, GO TO HIS OFFICE HOURS.

Yanez was a very good professor and did a good job of teaching the content. The class was challenging, but the difficulty was expected. If you pay attention, learn the content, and do the homework, an A is achievable.
