So, I've been accepted to two schools. One of them has given me pretty generous financial aid, and the other (which I would rather go to) is being a bit slow about financial offers, but I am apparently pretty high on the wait list. Unfortunately, as we all know, April 15 is bearing down rapidly on us. Would it be totally un-kosher to accept at the latter school to give myself more time to get hit up on the wait list, and then back out if I don't get a decent financial offer?
