Rough numbers - about 2,400 were totally qualified AND have a nomination. About 1050 of these will be admitted. Again approximate numbers:
Class of 2016
From House of Rep 435
From Senators 100
From Service Connections (Presidential, NG, Active, Rotc etc) 300
From NWL (by law) 150 (mostly LOA people)
That is 985 people. The Class of 2016 will be about 1050
That leaves on about 65 slots to "round-out" the class. These will be mostly minorities and "underepresented groups"
As mentioned in other posts, there will be 50 or so slots opened as people decline their offers (May 1 deadline to accept). Therefore, about 50 of you that are still waiting will get an offer within the next 2-3 weeks.
