Do schools stop you from actually learning?

Thanks to the generosity of my company's founder, I am able to work full-time while still being allowed to go out of the office during the day to take classes and try to get a second degree (Government). Lately, I've been noticing that most of my REAL learning comes from me just reading books on my own at night after work, and looking through posts on WSO. Most of the work I have to do for my classes doesn't really help me since I already know the information reading for fun. They take up a ton of time, adding to my already long hours.

Did you guys actually learn anything from school, or it is just something you just have to do?
