I took Math 31B with Professor Andrews, and I must say he's one of the best math teachers I've ever had. I really enjoyed his class.

His tests were reasonable, with the first midterm being very easy. Each test increased in difficulty, but that is to be expected of course. Go to his office hours! He does homework questions and clears doubts. His midterms are similar to the homework in difficulty. To get an A, make sure you are in the top 30% of the class. He gives an A+ to the first and second ranked student.

Paying attention in class is really easy, because he is very engaging and funny.

10/10 would recommend again.

Fantastic Professor with an interesting approach to teaching. Lectures are engaging and funny.

If you have the opportunity, definitely take Professor Andrews for Math 31B. I had him last quarter, and it was easily my favorite class. The concepts aren't all easy, but he gives incredibly well prepared lectures, and he hosts better office hours than any other professor I've had. If you're prepared to put in a little effort and ask questions, you will have a great time in this class, and you shouldn't have much trouble getting a a good grade, his tests are very fair. Not only is he clearly intelligent and hardworking, but he's also really kind and funny during his lectures. Bonus points if you get Alex as your TA, he's also fantastic.

The class is difficult. You must do homework and attend class in order to maintain a good grade. Mess up on the first midterm and you don't have much wiggle room. (This happened to me)

I always enjoyed going to Andrews' lectures. He kept lectures entertaining with his hilarious sense of humor, and really made sure that his students understood the material before he moved on. He explained problems step by step, but I will admit that the problems we did in class were much easier than those on hw and tests. As long as you know how to do the hw problems and go to his test review sessions, you will do fine on the test. The class is curved relatively well (I got a 79% and 83% on the two midterms and still got an A).

Class is composed of weekly homework assignments, two midterms, and a final. Midterms are difficult as there are only four problems on each, but there are many points for each problem. Definitely recommend taking Andrews for Math 31A.

Professor Andrews is among the best math instructors at UCLA. He has a genuine enthusiasm for the material he teaches and attempts to build an intuitive understanding of calculus beyond computation and formulas. Very fair grading, you get points for reasoning and don't lose too much for silly calculation errors. Both midterms are about as difficult as the harder homework problems, the final is definitely much harder than everything else but that's to be expected so make sure to study well for it. Office hours and discussion sections are actually worth your time, I learned a lot! Math 31B with him was definitely memorable. Lesson- Ace the midterms, get 100s on them cause the final will probably be difficult.

TAKE THIS PROFESSOR WHATEVER YOU DO. i will provide details but if your just skimming this page, then just know whatever you do, take him at all costs. Ive had the pleasure of taking andrews for both 31a and 31 b and i wouldn't be sitting here writing this if i truly didn't feel like this is one of the best professors at ucla. The fact that he is still fairly young makes it a lot easier to get a real relationship with the professor. He is an insanely smart man who will push you to truly understand math rather than just plug in and chug out some numbers. He makes you want to do mathematics which is hard to find in a math professor these days.

Andrews is the best!!! If you ever get over the fact that he is super british (but really why should you because it just makes class way more fun), he's also crazy smart and a nice guy. I didn't go for a lot of his lectures because I already learnt the material, but sometimes I just went because he lends a lot of perspective on what he's teaching. It's a breath of fresh air if you're the type that just memorizes the formulas and steps and hopes to scrape by, He's also really hardworking (which is such an underrated trait for professors to have) and he provides practice exams and handwritten notes for us to study. Not to mention he seems to be on piazza 24/7. His tests aren't easy but they don't mess around with you either. They really test your understanding and there are no cheap tricks (in the final he literally added a question telling us to check our previous solution for an error that he suspected we would make). TAKE ANDREWS.

TAKE ANDREWS HE IS AWESOME!!! He is one of the best prof I have ever had in ucla if not the best. He really cares about students, giving a lot of office hours. You can find HW TYPE problems in both midterms and finals so honestly if you put work on it you will be fine. TAKE HIM!!! I took Sudesh for Math 31A and honestly, he is great as well, but he really loves conceptual questions, which is way different from HW. Compared to Sudesh, Andrews is a very standard math professor and if you look for learning something as well as an easy B, take him! (Sorry I just got B cause his final is easy and I lose point on a question exactly come from the HW)

Andrews' lectures are funny & engaging. His tests can be challenging, but only because he wants to ensure that we've mastered the material (rather than just memorizing some formulae). TAs are usually great, HW is time-consuming but it helps a lot when you're prepping for the final. Also, he has notes uploaded for most topics, which are helpful (especially if you haven't been to class).
