We thought we read somewhere that there was a particular date that once you pass it you cannot be turned back (not sure if that's the correct terminology) if you get injured. We are trying to finalize a backup plan and one of the colleges require a new student conference. We are not sure which session to register for, and would like to push it out as far as possible - hoping DS gets accepted to USAFA. We have read about unexpected injuries resulting in plan B all of sudden becoming plan A because of a turnback. Just wondering what that magic date is - if there is one.
