PSTAT120B . 19 Days Ago

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.

She's nice and her midterms and final weren't that bad. Just do the homework and practice it and you'll be more than fine.

PSTAT120B . A Month Ago

Professor Ravat has a unique teaching style, but if you engage with it, the class can be manageable. The exams emulate the homework, and the use of a cheat sheet helps. Unstuck AI and other study tools proved invaluable for preparing.

Besides extra credit not helping, I don't think there's anything to complain about. I think she's actually a really good professor. The practice test is really helpful and the exams are similar to the homework so just make sure you understand hw and you'll be fine.
