Here is my post from last year (nov. 2011) about the sequence of events for my DS:
"For others who may be wondering how the timing works, my son was notified on Friday (11/4) by email that he had received the NROTC scholarship. His status was updated when he checked it online as well. His letter and DoDMERB application arrived in the mail today (11/7); his letter is dated 10/27/11. His acceptance must be received by 11/18, so that's only 11 days from now. He is supposed to contact the doctors for appointments within 5 days of receipt of the letter."
