The college scholarship is called an ICSP (In College Scholarship Program). It is tied to the det., follow Aulysses's advice and talk to your cadre. The scholarships do occur, but you need to be competitive.
What does that mean?
It means a strong cgpa. A 2.8 even as a STEM major is probably not going to cut it since the avg cgpa for SFT aka LEAD is 3.1 for STEM
It means a high PFT score. Think 95-97+. Running a 7:30 mile is in the boundary, but close to the max for a male. Running a 6:45 mile will look better
It means volunteering for everything within the det. If that means volunteering to clean up the det lounge on a Sat. morning at 8 a.m., you will be there.
Typically only less than 20% of all freshmen will enter with an AFROTC scholarship. Hence, why I say you need to be competitive because you now will be competing everyone else for that ICSP. ICSPs are tied to the det. They have a very limited amount of money to hand out. Yes, it does happen, but it is not a given.
