I read occasionally that some candidates receive notification of appointment after the April 15 deadline for USNA, all the way up to I-Day. The website says all candidates will receive notification of their status by April 15. I'm not sure I understand what that means. How many different statuses are given by the April 15 deadline - TWE, appointment, and what else - a waiting list? I hate to think that a candidate gets a TWE, moves forward with alternate plans and then receives word in May that he has an appointment. How does all that work?
