How to get back or even with a b**** college teacher?

So i got stuck in this anthropology cl in college and the teacher is from the Czech Republic, now no offense to people from there but she is just a big jerk. She has some very strange teaching methods, always extends cl a good 10-15 minutes after its over and scolds us if we leave (some of us have cles to get to across campus and jobs as well). Her accent is very bad and hard to understand, but the thing is she words her tests very confusingly (just like the way she talks) and when i confronted her about it she told me i was wrong and that i just had to study harder. Does any one have any ideas on how to get rid of this b****? and dont say drop the cl, its too late for that.
