Like Scott said above, if you can afford to go to college pay for it and then go get a pilot slot. There is a whole lot of information out there on this subject. If you need specifics on where to get it-PM me. Bottom line...there are many ways to get a pilot slot. If you want to go active duty then I would in order of preference:
Finish college on my own (assuming that money is not a huge factor) then apply for OTS.
ROTC-have someone else pay for college but risk not being a pilot if you aren't selected.
