I hate to say it, but chances are slim to none if you ask me. In order to reapply for SNA, you need to wait at least six months or SIGNIFICANT IMPROVEMENTS have been made to your application. Significant improvements include bumping your GPA, ASTB scores (significant gain), ref letters, interviews, etc. Bumping your ASTB score a couple of points isn't a significant improvement. For SNFO, since you technically didn't apply, you can submit a package for the October board, but even if you do get selected, it will be extremely difficult to get a FINSEL in on time.
