First off, an Army Recruiter is very rarely a good source for Army ROTC information (sorry all you recruiters out there). Talk to an ROTC Battalion ROO or Enrollment Officer.
If you aren't happy with your SAT scores I would hold off on completing your file and conducting your interview until you take the test again and get your scores back. Once your file is boarded it is tough to change your files score. If you wait your will miss the first board, but you will hopefully be more competitive for the second board.
