RepIII,
Relax! You will have well into the spring... and also if you get a last minute appt to an academy after you have accepted your scholarship then you can get out of your scholarship to go to the academy.
Also, if you accept a 4-yr scholarship and were not appointed to an academy and re-apply the next year, get an appointment you can get out of your scholarship. It is a viable option for someone who does not make it the first try.
In fact, at least for AROTC, you are offered a scholarship to a specific school by that ROTC program. You can be offered the scholarship before you are accepted by the school. The possibility exists that you could be offered a scholarship and not be accepted. So choose your schools wisely!
The ROTC program will work around you if you are an athlete.
Go ahead and get your application done if you have not completed it already!
