I just worry about if I pay off too much at once, does that throw up any flags to have me investigated though? I've still got time before I finish with school but I'd like to get on with my life and not be worried about being in debt... maybe I am just paranoid haha.
No such thing as paying off too much at once; you'll have less to payback, and the interest will affect it less, so it's better to pay it off as much as you can monthly (or whatever the arranged payment cycle is) until it's completely paid off. If it's subsidized, you don't even have to worry about paying it off till after school, since your school pays the interest for you
