Took this course last quarter. Not an easy course tbh especially for the beginners, but totally doable if you put tons of efforts in. Attendance is not mandatory, but you basically can get a curve if you attend most of her lectures. She is a very caring and sweet professor if you been to her office hour, and a very sweet person to talk with.

Don't take her class.

Only bad thing I would have to say is lectures were hard to follow. HW I thought was good at making you understand the concepts, but it is graded harshly so keep that in mind. OH were super helpful and if you want to boost your grade always cover the hws in OH. Tests are really easy if you know the material.

Very poor lectures that are full of mistakes and inconsistencies. She doesn't seem to understand the material well and it shows. Does not prepare you well and you will learn very little during lectures, even though most of the hw, slides, handouts are all taken from UCSD's CSE 20. The difficulty of the final was fair but expect to self study.
