Always Always Always ALWAYS ALWays Always avoid this professor. Always avoid this professor. I can't emphasize enough how important to not take his class and save your GPA. This professor has HORRIBLE and RIDICULOUS grading policy.

First of all, he does not curve the score. You may say, not curving the score is not that bad right? Trust me, not for this professor. I have taken some lectures from other professors who do not curve the score, but they try to make their tests fair and make the average around 80. For Ouellette, lol, the average for the first two midterms is around 65. The average for the final is 66, but he DOES NOT CURVE the fucking score, which means almost half of the class will fail.
The worst thing is not only his grading policy, but his TA (Eric Prizomic, do remember him) . This TA does not know anything about Math. I went to his office hour once and asked about homework problems, he can't explain shit. During discussion, he even asked students for help because he didn't know how to solve the problem. And his discussion is a complete waste of time. This TA is also EXTREMELY strict on grading homework and exam problems. The only thing he knows is to follow the solutions he did himself, and if anything on your homework is different from his solution he will take points off.

131A is one of the most difficult classes among upper math classes. It is a class about proving, which means on your exam and your homework, it is hard for us to give a perfect proof during exam. They can take off points anywhere they like.
Making his students get low score seems please this professor and his horrible TA. Taking this professor's class is one of the worst decisions I have ever made during my life. Try to avoid this professor.

Professor Ouellette is a nice guy. His workload is heavy but quite useful for exams. Although he speaks very fast, all his exams are extremely easy, and he highly emphasizes the process of solving questions. Just review homework solutions before the exam. Recommend his course.

Professor Ouellette was fantastic!! He is sooo helpful at his office hours and even in class. He genuinely just wanted everyone to do good. His explanations are very clear and sometimes proofs get boring but the exams were mostly computational and super fair. Final is just like the midterms too!

I took this class over the summer and was worried that the professor was going to go over the material too quickly. Although it is fast paced compared to a normal quarter, it was the best lower division math class I've ever taken at UCLA. Unlike most professors, the final was not hard and similar to the midterms. Recommend taking him if you need Math 33A.

Everything is expected in this class. For the final he even reused old exam questions from the midterm. If you just do what he tells you to do you should get a pretty solid grade for this class. There is no hard questions or any new material he didn't cover in lecture in the exams. I recommend him.

Midterms and final are straightforward for the most part, so don't expect any curveballs. I fell behind on the material for the class second half of the course, but it's not hard to catch up.

Although he is a nice guy, but if you want someone who has real insight to mathematics like Terrence Tao, this is not the guy you want teaching you. I recommend another professor and to not trust his bruinwalk rating.

This is an easy class. Tests are very straightforward and his lectures include very clear examples that you might see on the homework or exams. He's a very good lecturer -- I didn't feel rushed at all despite the class only being 6 weeks. I didn't study a single time, frequently skipped discussion, and did the (long-ish) homework the night before it was due and still got a B-. Put in some effort and this is a pretty easy A. Highly recommend taking 33A with Ouellette.

The amount of material you go through each week might feel overwhelming since it's a 6-week summer class, but the tests are very straightforward. If you do only the homework and fully understand/memorize how to do computational problem-solving processes and the more important linear algebra definitions, you'll be adequately prepared for the tests. (I ditched almost all discussions.) The final basically reused questions from the midterms, and the midterms basically asked the same questions as the homework. I do think that the grading is pretty strict, since I made a silly mathematical mistake on my second midterm that messed up the rest of the problem, and I basically missed all those points. (Each midterm had 5 problems, each problem worth 10 points.) As a result, I got a bad score on the second midterm (72%) compared to my first one (92%). However, I learned from my mistakes, aced the final (which was 2 hrs, 8 problems), and managed to pull through with an A.

As for the class itself, expect to sit through a lot of proofs of the more minor theorems you won't really use; it's incredibly easy to zone out. Ouellette is pretty kind-hearted, approachable, and genuine from what I've seen, but you won't get to learn anything in-depth about linear algebra because of the rush to cover all the content. Overall the class kinda felt like a rushed high school math course. If you just need to take this class to fulfill engineering reqs or something, I highly recommend it, but if you want to feel satisfied that you've learned something significant and useful, you should probably take this class with a passionate professor during the academic year.
