I visited an AFROTC det recently, and a member of the cadre told me that the vast majority of engineering majors in the unit take five years to graduate. Which isn't surprising considering that many engineers--in ROTC or not--do take five years... but scholarships are only four. This doesn't make sense considering that many, if not most, of those scholarships go to engineering majors. Why would the AF offer four year scholarships to cadets who are expected to take five to graduate? Can they be extended? Or are engineers still generally expected to graduate in 4 years, and the det I visited was just an outlier?
