I was pretty shocked by the low reviews. Prof. Kassab is a very fair and kind instructor. Some may complain that the tests were "proof-heavy", sure, but it's not like these proofs were hard at all. There were really only 6-8 of them that you needed to know, and she went over every single one in class (or left it as an exercise that can be found in the book). Really - not bad at all!
She gave us a practice midterm which I found helpful. I didn't do too well on the midterm because it was rushed and I made some arithmetic mistakes. (Unfortunately, the exam rubric punishes arithmetic mistakes heavily, so be very careful in your calculations!) However, she has a fantastic, forgiving grading scheme that allows the midterm to be replaced by the final. During the final, there is wayyy more time than the midterm so you can do better.
Another thing I found really helpful was that she gave us a list of final study topics. I don't know if it was just because we were online for 1.5 weeks this quarter, but she ended up cutting out a lot of content in the final, which made things super clear. (I think our final was lighter on content than the other 164 class.) She also gave an extra credit opportunity on the last homework! Pretty sweet. But, once again, idk if she only offered this to us because we were partially online.
Finally, one more piece of advice: whenever Prof. Kassab recommends a proof, DO IT.
Overall, Prof. Kassab is helpful and wants her students to succeed. It is really clear she cares about her students. She would even show us coding examples of some of the algos, which I thought was pretty cool. I am really glad I took this class.

The prof sucks. I liked the class material, but the prof made me not like it. She never responds to any emails. She only teaches the minimum, barely any examples or anything close to the tests. She refused to give us practice exams, telling us to just see the book. The TA carried the class, he was great. The prof was very bad. The math department sucks in consistency of quality of professors as well as grading. I think she said she wouldnt curve, even though the average on the midterm and final was C- (71~72%).
She purposely isnt allowing regrade requests for the final for some reason, her grading sucks (since I've found multiple mistakes).
If bruinwalk would allow me to have helpfulness and clarity as 0, I'd give 0

I attended pretty much every single lectures because she doesn't post any notes or slides, just recommends you to read the textbook. Her notes from class did end up being pretty helpful for the homework and studying later on, so it was worth attending. There was 5 homework assignments for the whole quarter, though I am not sure if she reduced the amount due to us going online for some time. Overall, she was a very nice professor and was always asking the class how we were doing and what she could do to help us (especially when the protests started happening). I failed the midterm, which was my fault because I didn't study enough, the class average was an 83% for it. But thankfully the second grading scheme saved me, and I got an 80% on the final, which was graded very generously. Overall, I think if you just show up to class and do the homework to study, you'll be okay.

It was her first quarter teaching at UCLA (i believe) and her teaching is pretty mid. I noticed her lecture notes are just watered down material from the textbook and you could easily get by with skipping lectures, doing hw, and reading the textbook or something. Stopped going to lectures around week 2 and never went to discussion and passed, if you have senioritis like me then you'll love her lol

We needed to use practice tests from other classes because she refused to give practice problems. She wouldn't even give us solutions to the HWs and tests. She made it very difficult to learn the material. Even though a class might be hard, professors will try to help accommodate students to help them learn, but it felt like she didn't want to help us out.
