And it doesn't really help because you know which professors are bad and you might just have to take a class from them anyway. We did have a really bad professor in my department who got me fired for something stupid. (I was a lab admin). A bunch of students came to defend me. Her husband was the chairman so all of her evaluations went through a different department/chairman. She got enough complains they didn't grant her tenure! Her and her husband left the university shortly after. I feel like the students achieved something really positive there.
