I got waitlisted last year, and within a week (more like days) they called me and said there was a spot.
And now I have been accepted to the Class of 2015. And I found out REALLY early compared to others. I got a letter of assurance back in December. So yeah, you can use Summer Sem as a comparison to where you may stand when applying next year, but the SS application is SOO vague compared to the actually academy application. f you have any questions, private message me.
