I'm going to assume that this is a WIP, and just want to know what's up with the age/year combo? 17 is usually the age of first semester seniors (12th year) and the usual age of incoming 9th graders/freshman is 13/14. Nothing wrong with leaving it the way it is, but you'll have to get a reason for him to be that age, be it some shit going down outside of school removing him from it for a few years or just poor grades.
