One of my students, a sophomore, was accepted on Monday also. I'm sure more invitation will be forthcoming. Don't be disappointed if you miss receiving an invitation. Based on your current status, you may want to reapply and/or apply to the summer seminar when you are a rising senior. One other way to experience USNA is to attend one of the summer sports camps there. You stay in the dorms, eat in the mess hall, meet middies and work with the coaching staff. I have had a number of students attend sports camps at all of the SAs (except USMMA, which does not have them). All of the students enjoyed their visits and experiences at the camps. Best of luck with your application!
