Spend the next 4 years studying your brains out and graduate with a 3.7 or better. Also during the next 4 years spend a bunch of time researching ANG and AF reserve fighter squadrons. Contact the squadrons that interest you and bug them about a job.
Don't bother with ROTC or active duty. The best deal out there is getting hired by the guard or reserve, they will send you to Officer Training School (12 weeks), you'll then go to pilot training, fighter training, and then you will back with your guard or reserve unit full-time for a year or two, then you'll transition to part-time if you so wish.
The guard and reserve hire college grads off the street and send them through training all of the time. There is no better way to become a military pilot.
The Navy and Marine Corps may have a similar program, I don't know. Any input Navy and Marine bros?
Good Luck,
