Dude, you are posting on an internet forum, not a crystal ball. It could go either way. I've heard of people getting into GW's waitlist the day before classes begin, but I wouldn't count on it. At this point I would be ready for your fall back school and if GW works out, be happy for it. Though, getting an apartment in DC that short notice if you aren't from here will be expensive since you will have to take whatever you find.
