There is an additional issue to the gpa besides losing the scholarship. As an ROTC cadet, you will need your commander to support you for your life as an officer. For the AF, don't pull a 3.0+ you can kiss UPT goodby. Your gpa will be a big factor on the track you will be selected for as an active duty member. Similiar to the SAs, the higher your class rank the better the chance you get your dream job.
