For a calculus one class, it was the easiest advanced math class I have ever had.

Would take again

lectures are kind of all over the place and i never understand anything in class so i have to spend a lot of time outside of class teaching myself. also theres a lot of hw. shes funny so at least not super boring. also she curves tests and offers corrections so thats a BIG plus. we had like 3 quizzes through the semester and they were very light.

Lots of homework
Hilarious
