I enjoyed the class and the exam. The only thing is he writes extra of notes on the white board... Also, highly recommends TA JOE!

Andrews is really helpful and an overall great professor to take this class with. He holds a lot of office hours and guides you in working out the problem on your own, rather than just answering the problem for you. He has really good TA’s too, who also are very good at explaining how to do the problems. The only problems I had in this class was that he assigns a lot of weekly homework, which is graded, so you need to get it done correctly and on time, and that his tests are pretty difficult if you don’t understand all the material completely. Overall, to pass this class you just need to do the homework mindfully, and go to his office hours and review sections to help you understand the content.

Andrews was a very tricky professor. His lectures were decent but his tests are difficult and anything but straightforward and he will purposely give you more difficult questions and expect you to think outside the box. If you want an easy A and keep moving forward he is not the professor for it. He does not hold review sessions and he gives out a bulk of HW from the textbook. The problem was that his tests are nothing like the homework he assigns.

Andrews is a very funny professor who obviously was a super genius that knew the material by heart. However, I felt like lectures went way to quickly when going over hard topics and I wish we slowed down in order to get a better understanding. But Andrews helped in review sessions before the final, which I greatly appreciated.

Professor Andrews is hands down the BEST professor and overall human being I've ever had at UCLA, and I'm not even exaggerating a little bit. I had him for 31A and 31B and he's hilarious, super intelligent, engaging, straightforward, and very nice/approachable. He somehow manages to make my least favorite subject in the world not only bearable, but almost fun. I would highly recommend taking any of his classes, I wish I could take more of them myself. If he taught all of my math classes, I would probably be a math major by now. Love you mjandr!!

Professor Andrews is a super reasonable guy. He was super understanding when I had some health issues come up right before a midterm. Although the tests themselves were difficult, he did a great job of teaching the harder calculus topics that I did not understand when I was taught them in high school. The only thing I struggled with was when he lectured and I felt like the examples he gave were a lot easier in class than on the homework and tests. But overall, I really liked him as a person.

All right. You’ve heard the fantastic reviews below mine, as well as the glowing recommendations on the UCLA Math major Facebook group. Your first pass, even after declaration of the math major, was also thankfully (but barely) good enough to land you a spot in Andrews’s lecture.

Now that you made it, what to expect? Your grade is determined by 5 quizzes and the final. Quizzes? Hard as flying &$@£, but do not fear. The grading scheme makes it so that you always have 100% on your quiz category, but the worse you do on the quizzes, the more your final matters. So you could get a 70 average on the quizzes but if you get a 90 on the final, you’ll get about a 93 in the class. The averages/medians were low on all exams (<= 60), so it’s important that you get ahead of the curve. No oral final for this quarter and probably subsequent quarters because the math department didn’t follow through with having oral finals.

Lecture-wise, you really can’t ask for much better. What I will say has already been said in the other reviews.

As for how to do well? A general pointer: you have to BREATHE the material presented to you in lecture. Every major concept, you must be able to manipulate and command swiftly. Study the quiz preparation materials as deeply as you can, and try to develop a strong intuition by solving the problems yourself as quickly as possible. If you do not understand a concept, you will be heavily punished for it. For instance, he did this thing with true/false questions where you would get NEGATIVE points if you guessed incorrectly (so the questions could potentially dock points from OTHER questions if you put in too many incorrect responses). Since this was so stressful, I’ll offer some tips. First, you need to ingrain every major theorem and quiz prep result in your head. Every single clause/hypothesis of a major theorem, you need to play with and commit to memory so that you know if a true/false statement seems off. Draw pictures for these questions to see if you can find counterexamples. Do not use theorems in answering these questions until you are entirely sure that their hypotheses are satisfied. It is immensely painful to realize that you got negative points for a question because you accidentally cited a theorem or thought you were right when in reality you weren’t.

And lastly, the final, I would argue, is a fair exam, aside from those damn true/false questions, as knowing the concepts and studying the quiz prep should allow you to do well. Since a good score on the final will ENSURE success in the class, you really want to take the time to, again, learn how to breathe the material in 131A. Understand the workings of epsilon delta proofs, as well as when/why you would use max. Same thing for limits of sequences. Hammer the formal definitions of differentiability and integrability into your head. I know it’s going to be tough, but by really developing that intuition and learning as much as you can from your quizzes, you can pull greatly ahead of the curve on the final. Andrews is an amazing professor, but to do well, you must put your best foot forward and push yourself to master the material. 131A is a juggernaut, so take advantage of the lectures and the resources that Andrews gives out to you.

I never write reviews, but Professor Andrews is too fantastic of a lecturer to not write a review on.

First of all, his lectures were super engaging and concise, and made the course material seem less dense and dull. His entire lecture notes (about 110 pages) were also available on the course website. I personally loved his lecture notes as they were almost identical to the lecture and were very very clear. He also spent the first week mostly talking about quantifiers to make sure that the students had a firm understanding of statements and proof structure. As this course was mostly about proving whether a given statement is true or false, having a strong foundation on the quantifiers and proof structure definitely helped for the quizzes and the final.

There were 5 quizzes on even weeks (2, 4, 6, 8, 10) and a final exam. All the questions from the quizzes and the final exam were based on the lecture notes and the quiz preparation problems. The solutions to each quiz preparation problem sets and the quizzes were uploaded on the course website fairly quickly, with great clarity and detail. Professor Andrews was also extremely helpful during office hours, and he would answer any questions that come up very thoroughly and made sure the students resolved their questions and were content when they left his office.
