There was a thread about this last summer, I think, that referred to the waitlist from a previous year. I believe the percentages quoted were in the 50-60% range (coming off the waitlist). It also mentioned the waitlist consisting of only about 30 applicants ... but I don't know how good that info is. In general, it can be said that the GW waitlist does see good movement. I am on the waitlist too, and if I come across some reliable information, I will post it. Good Luck!
