My son was admitted into several of his Plan B schools before receiving his letter of admittance to USAFA. After he received his LOA, and had accepted, his ALO recommended that he notify his top Plan B school that he was planning to attend, but ask for a deferral from Fall Session to Winter Session. This way, if something happened before I-day (got hurt, got sick, etc), or if, for some reason, he didn't make it through BCT, he had a backup beyond Community College. We are about to cancel this for him in the next couple of weeks.
