Disclaimer: I don't consider myself good at math.

Hazel's teaching is pretty good. She's clear at showing what format she wants proofs to be in and makes sure to go over many examples that pop up in the homework, so as long as you look at her examples, it won't be too bad. I found it a lot easier to listen to lecture than try to understand the textbook for this class, while the opposite was true for my other math classes. She also recorded her lectures.

She "assigns" many homework problems, but you only have to turn in three or four per section, so most of them are extra practice. The problems themself aren't hard, but because this was my first proof-based class, I didn't find them easy, either. I would definitely do the extra problems because similar ones appear on tests. The lowest homework is dropped.

Her tests were pretty straightforward in terms of difficulty; there were only one or two problems where I was like "bruh". For Midterm 1 and the Final, she had a combination of open-ended questions and multiple-choice, while Midterm 2 was all open-ended. The lowest midterm is dropped.

Attending discussions is mandatory because there are weekly worksheets you complete with other people. However, she drops the lowest four worksheets, so you only have to go half the quarter.

Overall, I think this class was pretty good, though that might be because I took it while most things were still online. I would take Hazel's class again if given the choice.

Professor Hazel was definitely my favorite professor of the past quarter. She is super clear in her explanations and always takes the time to answer relevant questions in a helpful and respectful manner. The tests were pretty straightforward and the workload was entirely manageable. I think that the grading was exceedingly fair, as there were 4 grading schemes from which the best grade was chosen to calculate the final grade. That said, this is a pretty proof heavy class, so emphasis is put on the style and format of proofs, and that is taken into account in grading. I'm not sure how much different that would be with other professors though, because I think proofs are pretty central to the content regardless of who is teaching it. Overall, I absolutely recommend taking this class, or any other, with Professor Hazel.

TL;DR: Overall, would recommend for people enjoying math and would not for people taking this class to pass.

Prof Hazel uses a very hands-on, systematic approach to learning discrete math, one of the hardest yet most useful branch of math. I would recommend taking this class with her if you are:
- constantly on top of your schedule and work;
- asks questions and clarifications often
- likes proof writing and analyzing problems.
Her style of teaching emphasizes proof writing and writing complete sentences, which is undoubtedly very useful for advancing onto harder upper-div maths. However, if you are just learning this to have fun and absorb useful knowledge for CS, I would rather take this class with an alternative professor that is more lenient with grading and lets you have more fun with the materials. The fact that this class was online this quarter really was a blessing as we have the option to look into textbooks and notes during tests. I don't know how the in-person lectures are going to be carried out, but it is likely going to be easier. Just make sure that you practice, practice, practice and have a system where you know how to prove each kinds of statement appropriately.

This professor was one of the worst ones I have taken at the math department. Her workload is not unreasonable, but her expectations from the students are. She expects students to replicate her proofs to the T, and if you miss something you are marked down. The grading is very harsh and can be demoralising for freshman, would recommend her if you are a sophomore. I honestly did not learn much in the class, and suffered a lot because of the harsh grading. If you want to score, pay attention to what she expects you to write otherwise you are screwed. Don't try to be creative or think out of the box as she wont tolerate it at all.

One of the most straightforward and effective classes I've taken at UCLA! Professor Hazel is great; she has nice handwriting and clear lectures, is incredibly organized, leaves time in lecture for questions/clarifications, and is also really helpful outside of class. I never left lecture confused, and although there were some homework and exam problems that were somewhat hard to figure out, I always felt I had the tools to succeed with them eventually (and this was the case!). Essentially, she teaches content well and then sets very reasonable expectations on the homework and exams. It's night and day with some of the other professors I've seen in the math department... If you have the chance to take a class with Hazel, don't hesitate! (Also, one of my favorite textbooks [Johnsonbaugh]; visually pleasing and fairly straightforward to read, for a change, even if the proofs can get a bit dense.)

Prof. Hazel is an absolute gem of a lecturer! She is really good at explaining the material, and her lectures are very engaging. This course content was super interesting, but can be a little overwhelming at times because it involves a little bit of proofs, and some more intermediate logic needed to solve problems. All the class examples, homework problems, and test problems were very satisfying to finish! Such a great introduction to both upper division math classes and comp sci algorithms!

Prof Hazel was a clear lecturer and gives great examples during class. The beginning of the course is harder than the end.
