PSTAT120B . 16 Days Ago

honestly one of my favorite pstat teacher. the first four weeks were hard but got easy at the end. midterm was hard but she offered 10% back and the final was similar to the practice and midterm. hw were hard but doable and she has weekly online quizzes worth 25%. she's so well organized and loves talking to study's. she really cares and sweet

PSTAT120B . A Month Ago

Midterm practice questions were not on the midterm. She is the worst PSTAT professor ever, so please do not take her if you want to pass 120B. Awful grading system, and she sometimes skips trivial steps so it is hard to follow along with her.

PSTAT120B . A Month Ago

Bruh half the questions on her midterm weren't even on the midterm practice Also she's pretty incompetent at almost everything about teaching: course structure, lectures, and just explaining things in general. Materials on canvas are frequently incomplete or removed so it's very difficult to review without AI or ULAs/TAs

PSTAT120B . A Month Ago

last quarter i had her and i dropped her class and it was honestly quite a lot better than this one, at least exam wise but this quarter she's regressed, and her class always has some stupid gimmick like incomplete lecture slides and then her lectures suck anyway because it's just a slideshow of a bunch of abstract formulas no actual context

She has improved significantly in recent years and has made a clear effort to do so. Her rating is so low because of mostly courses from years ago, but her classes are quite approachable now (I've taken 2 recently). Used GPT for lectures instead of attending which worked for me. Homework/quizzes weekly but they're helpful, exams were reasonable.

The homework is good practice for the final exam and she truly wants students to learn. She doesn't post lecture notes for a week or so, so if you dislike going to lecture probably don't take her. But I would say she is a great professor.
