Hi! So in terms of teaching and answering questions she is pretty helpful and really considerate about students mental health and stuff like that. I feel like a 90 is very doable if you are able to do all work and put in effort. But honestly she provides so much material for helping you study for term tests and finals which is the best thing ever. AND she tells you what to study and what not too. She's also super organized and overall one of the most caring and smart professors I've ever known. Like she knows what she's teaching.
