My son just received an appointment from his Congressman to USNA and USMMA. He has an LOA from USMMA but has not heard anything from USNA. I was wondering what his chances are of getting accepted by USNA with an appointment in hand ? Does it make it an almost assured thing or are there kids that get appointments but don't get in ? I know there are no assurances and the official party line is that it is a step in the process. I was just wondering if anyone out there went through the same thing ?
