Burton is a really good professor who clearly explains topics in class. If you pay attention during lecture, you won't really need to read the book thanks to her comprehensive teaching style. Lecture attendance is mandatory and iclicker questions count for 10% of the grade. Her lectures are recorded and slides posted.

Andrea is a new professor here at UCLA, welcome 👏!
She's a nice professor and cares about her students for sure. However, her teaching could be improved a little more; I am not even sure what exactly distinguishes a good professor and an excellent professor, but I'd say the "excellent" professors have more engaging lectures and explain things more clearly, and Andrea could work on that. It's only her first quarter though, and I'm sure she'll get better. I heard that her office hours are really helpful, but I haven't checked those out. Would recommend her 8/10.
