Well I'm still holding out a little hope that this is just the current "application complete" message since no one with a complete application has said that they have a different message. Last cycle several people got interviews after being placed on hold so it's not like it's the end of the road if my app is on hold... I was just shocked that after being complete for only 1 full business day, I was put on hold.
My GPA is probably why I won't have the best chance of getting in... besides that, they get a zillion applications so your odds aren't that great to begin with. I really like GW for their health care policy focus so I took the $125 risk. Good luck if you decide to apply!
