If you wanted to apply for ROTC you are a bit behind, but really if you go OCS you control much more of your destiny, at least for the USN, seen guys in NROTC that came into my office to take the ASTB and not get a qualifying score, they are still going to be officers but not just in aviation.
A friend of mines son went to the USAFA and is in pilot training, when he was home on leave he stopped by our office so we were talking, asked him some questions about who he sees in pilot training, he said mainly USAFA, a few AFROTC, and he couldn't think of any that were from AF OTS
Find a college you like, go for a degree that interest you, do well, then apply for OCS, there has been plenty of spots for those that have good ASTB scores and a good GPA.
