Thanks triathlete, I guess you're right. I'll give it a go (I have a feeling this may become a pattern!) I'm still waiting to hear from U. Mich too - I assume that I am also on their "wait-list." I left a phone message today - hopefully I will hear from them soon. (I went with my advisors' (multiple!) advice to wait until Dec 1 to make calls, but I'm beginning to regret that now!)
I called mayo today to find out why I hadn't heard from them and they said, "Oh dear - it looks like your application was placed on hold back in october because they were waiting for something to come in - and they haven't looked at it since. I'll ask the director to look at it again" I'm not sure what that means - but it can't be great.
I think the whole thing is odd. I got invites from cleveland clinics, u. cincinnati, UNC, U Wash, OHSU, Penn St, U Wisc, UVA and other smaller ones. So far my only reject was duke - and frankly i didn't intend to interview there anyway! I don't know what the story is and why i'm good enough for some of those, but not colorado!
I guess I should be happy for what I have! It's just that colorado, mich and mayo were three of about 5 places I really felt strongly about. As for the rest, well let's hope they surprise me!
