As a transfer student/cadet I heard you can become a commissioned officer via both routes, however if you want to contract do you have to do so by the end of your MS 2 (or sophomore) year? is that also done on a competitive basis? I was also told that in order to go MS 3 or MS 4 you would have to be a contracted cadet is there any reason behind that? can one also get the AROTC Scholarship as a junior or senior? thanks!
