Car accident claim as a student?

I'm a college student who was injured in a car accident that caused a concussion resulting in me missing 3 weeks of class, having symptoms for over a month and having to drop 3 of my 15 credits, what should I be seeking as far as compensation?
Update: Update: I was found 100% not at fault, I was rear ended on the highway
Update 2: My only injury was a concussion, which the treatment for is laying in a dark room doing nothing, I have a free clinic on campus, my tuition is 21K but I pay 14K because of scholarships, they have already payed to have my car fixed.
