My DS received a 4 yr AROTC scholarship last year. Originally he accepted the scholarship but then he turned it down in July of 2011, letting both the university and Cadet Command know of his decision. My son has changed his mind and would like to join AROTC at the same university and compete for a 2 or 3 yr scholarship. My question is: is he still able to compete for a scholarship or because he had one and turned it down, he would be ineligible to compete for another one?
