Have a Berkeley math degree. Two observations. Student ratings are whack. I had a professor I thought was really good but had an average rating. I had one fellow student state that he hated the professor. I am pretty sure the professor did nothing to him that deserved that hatred. People don&#x27;t like it when they don&#x27;t do as well as they expect. Second, it appears that the math department hires based on research because I had a newly minted professor who was just plain indecipherable.
