PSTAT120B . 22 Days Ago

Professor Ravat is literally the easiest teacher I've ever had. The midterm was exceptionally easy, and she offered 15% extra credit on the midterm since students didn't do as well as she wanted. The final was easy, and shes organized and dedicated to helping her students. The class requires bare minimum study, especially for an upper div course.

Bro I left a good review, don't take her, she's sweet but her tests r evil and everyone did so bad the average was a 50% and she still didn't curve and she said oh the test will be so easy, no it wasn't it ate me and spit me up and no curve just her “generous” 2% extra credit, don't take her unless u can teach urself EVERYTHING

Avoid going to lectures, you won't learn anything. She puts random complex formulas (slides) without properly explaining how they work. To get an A, put the lectures into gpt, ask it what formulas to memorize based on what criteria the problem gives/asks for and how to solve. She is entitled & can't teach (hence the rating) -also didn't curve.

Those who say the comments are racist and biased, there is definitely a reason why among many other professors, Uma is one of the ONLYs being rated at a low score.

Never post or claim anything about the midterm/ final average or median. She acts out being so nice and caring. The so-called extra bonus isn't really boosting anything. She is performing so hard to say "I wish you all succeed", and still making the grade as tough as possible.

Honestly I never EVER write reviews but she is such a sweetie and want to tell anyone that is thinking of her to take her. She is so caring and wants success for u, she offers EC, Online Quizes, HW that was graded easily. Yes her midterm was little hard but she understood we struggled and offered EC and modified grading. TBH people r racist & mean
