ED is binding meaning I must go there. does that mean if during the spring I get appointed will I be unable to do that? Obviously I'm going to choose USNA in a heartbeat but I've heard rumors of students who back out of ED getting blackballed, meaning the school will notify other schools and give them a bad image. in some cases, people lose their entire acceptance to other schools. On a slightly related note, I've also been applying ED to like 4 or 5 schools so far and I'm told that's dumb and I need to change it is that true?
