PSTAT120B . A Month Ago

Good professor with fair grading criteria. Gives practice exams that are similar to the real exams. Kind lady with a real passion for teaching. Brought cookies for our class and gave them to those who participated

Tbh a kind and caring professor. Do not understand the hate on here, she's a very nice lady and definitely cares deeply about her students.

PSTAT120B . 2 Months 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 . 3 Months 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 . 3 Months 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 . 3 Months 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
