ROTC and the SAs are for high school seniors. OCS is for those getting ready to or have graduated from college. OCS procedures are relatively straight forward and administered by the local recruiting offices. I am not sure what we could do constructively to help.
Ditto what USNA69 said. This site is concerned primarily with the Service Academies, but we decided to throw in some ROTC discussions because they provided like-for-like alternatives (well, sort of) to them.
