I don't think so rush. getting in after getting rejected doesn't mess your chances up. You probably weren't rejected for not being qualified. There was just too many applications. Anyway the miniumums for the ASTB are low. the official ones are like 3,4,4 AQR, PFAR, FOFAR but the board I guess is looking for 6,7,6. but the official ones ar still low. So you look like you got rejected because of too many applicants. I think that this will actually help you in getting in the next time.
man the wait is killing me
