@dayna: I concur with the assessment of Vandy as probably being out of reach for you – at this point, anyway. And, yes, they would “turn up their nose” at a 30 ACT; I know a number of students with higher ACTs than that who were not accepted; you will probably need a 33 or 34 ACT to be competitive for admission there. Georgetown, Johns Hopkins, and W&M will probably also be tough for you to get accepted; but I second the suggestion of looking into GW, American, and Dickinson.
As the other poster stated, “there are lots of good fish in the sea . . . .”
