Allen is the BEST math professor I've had at UCLA. His lectures are super straight forward once you get used to the material, and those combined with the homework is everything you need to do well on his tests. His homework is super helpful but can be a bit tricky doing the problems for the first time. People did super well on his tests this quarter (he also gave us a very extended amount of time) with the average being in the high A range. That being said, I feel like even during a regular quarter his tests would be super reasonable and test you exactly on what he has taught you. Allen is so dedicated and offers a bunch of office hours, and will go so far as to schedule an extra OH on the weekend if he gets a lot of questions. He also responds to your questions super quickly via email or piazza. I would 100% retake this class with him, it has been my favorite math class. Also shout out to Jeremy Brightbill, the best TA with the most life-saving review sessions who will hold office hours until every person has asked every single one of their questions, even if it means logging out of zoom at 11pm.

I took this class online due to COVID-19. I technically had Hluschanka as my professor for this class, but since Allen and Hluschanka worked together to make the homework, exams, and quizzes the same for both classes and the fact that Hluschanka posted Allen's lectures on his ccle page, I watched Allen's lectures instead. I watched all of the lectures on at least 1.5x speed and I was still able to take notes and fully understand what he was teaching (he talks and writes pretty slowly). He goes through all the material thoroughly and is easy to follow. The exams, quizzes, and homeworks were all very similar to one another, and absolutely everything on them was covered in lecture. The material in this class is very easy if you have a good grasp of calculus. I'd say 33B, for me at least, was the easiest of the 31-33 series. I took this class concurrently with 33A, and I found that they worked very well together, at least with the order than Allen taught in. In fact, in weeks 1 and 9, I was practically doing the same thing in both classes.

Everything was computational and all the processes to solve every problem was in the lecture notes which were very clear and understandable. Lots of office hours that helped as well.

This is Allen's last regular quarter at UCLA. Good luck on his future academic career.

I took this class online due to COVID-19. The professor's lectures were easy to follow! He always explained any concepts from Linear Algebra we needed in class which was useful. Grading consists of weekly quizzes and homework which take up a lot of time but are very helpful for studying for midterms and the final. Midterms and the final were fair and were pretty similar to the hw. Overall, the class was a lot of work but the concepts themselves seemed easy! We also didn't need a textbook since he would post all the lecture notes on CCLE.

It's a shame that Allen will not be teaching here anymore, but I wish him good luck on his future academic career.

If you already have a good grasp on the basics of 33A (Linear Algebra) and single-variable calculus, this class will be very easy. His lectures were pretty slow, so I had to watch his videos at 2x and was still able to write down everything. He does explain everything in the course material well and his lectures are very easy to follow. The homework is decent in difficulty, although there were a few that, at first, had me a little confused. He does weekly quizzes based on the previous week's content, which I thought was a good way to reinforce past topics and keep them fresh while new material was being covered. There were times, though, when there wasn't enough time to actually finish the quiz and thoroughly recheck the problems (you only get 40 minutes to finish and upload). His exams were very similar to the homework in style and gives a generous 6-hour time limit so they were very fair game if you did all your assignments. Outside the academics, he does have very good taste in his shirt choices.

We will miss you Allen!
