As a double major senior student in ECE and Applied math department, I have took more than 30 upper div classes in UCLA and I never felt this lost in any of my coding, engineering or math classes. The professor doesn't know what she's talking about and I noticed she got all her notes and hw set from Professor Killip's fall quarter. Basically her lectures were the worst lectures I have attended (so I stopped going to live lectures after week 3 and read the book instead) and the test are ridiculously long, time consuming, and hard. My advise as a UCLA Alumni : AVOID HER AT ALL COST EVEN IF SHES TEACHING BASIC ALGEBRA

I had trouble following along during the lecture at the start of the quarter because she would start with examples first and try to teach the theorems or techniques through the example, but it became confusing what the exact theorems/techniques we should be learning are/where she was getting them. It got better throughout the quarter and I was able to understand the material pretty well after reviewing the notes again on my own time and working through the homework. I personally didn't find the textbook that helpful, and I would have to go to my TA's OH to ask for clarification on what the homework was asking for. The exams were pretty fair, but the final was long and tedious (24 hr format). She's not the best professor I've had, but the course material wasn't too difficult so I was still able to do fine.

Honestly, I was pretty worried because the professor of this class got switched to Professor Greenfeld at the last minute, and I know she doesn't have the greatest reputation in her lower division classes.

However, my personal experience with her this quarter was absolutely fine. Since this class isn't really theoretical at all and almost purely application-based, I thought that the explanations and examples that the professor went over in class were sufficiently clear. As for midterms/finals, while they were pretty long and time-consuming, I thought their difficulty was pretty fair, at least compared to some other proof-heavy 24hr math finals.
