As OC said you will do your Medical next. My son did not do the paperwork for the security clearance until he started school the freshman year. Keep in touch with your PMS at the school you will be going to. They will let you know about any orientation prior to starting school. My son went to school the weekend before school started, over the wekend he collected all his gear, met with the cadre and had orientation meeting that the parents were allowed to go to on Sunday. Each ROTC unit will have different procedures. My son was also invited to go to a weekend Land Nav training in the spring of his senior year of high school, so keep in contact to see if there are any opportunities for you. Other then that enjoy your summer and work out a lot, especially running....run a lot. One thing to remember is that you have until December to pass your AFPT. If you don't pass it when you start school you don't receive any stipend money until you pass. You only need to pass with the minimum score to receive the stipend...but...if you only have the minimum you will probably be on remedial PT until you get the score the Unit has set as their minimum. At my son's school you needed to score 80 on each section of the AFPT to stay out of remedial, and remember to AFPT is a lot harder then the presidential fitness test, if you don't do the push up and sit up exactly as the regs show they don't count them. Congratulations on your scholarship and good luck with your first year.
