I applied to 5 schools. The first 2 interview invites were for my #4 and #5 choices. I called them and told them that I would have to reschedule the interview for a later date due to travel arrangements. They understood.
Then, I got an invite for my #2 choice. I went to that interview. Got accepted shortly thereafter.
Got an invite for my #3 school, but was already accepted at my #2 choice.
Finally, an interview invite to my #1 choice. Went, interviewed, accepted.
I called the 3 remaining schools and politely declined my interview invitations.
I spend $46 in travel expenses for my 2 interviews. I would have spent around $750+ if I had gone to all 5.
End result was that I got into my top choice.
I have a friend who spent $8,000 in applications and interviews only to get into his top choice, a school 5 minutes from his home.
What's the point of all this? I'm not sure there really is one. Oh wait, yes there is...a very wise pre-med advisor told me "Don't interview at a school unless you would go there if it were your only acceptance." So...if it was the only school you got accepted to...would you go? If yes, then buy your place ticket. If not...save your money.
I'm not sure I would have gone to #'s 3, 4, and 5.
But that's just me.
Good luck.
And by the way...if you were offered interviews at the schools you listed, I am sure you will be hearding from the others soon. I have heard that CCOM is a bit tighter with the interview invites for out-of-staters. UNECOM you are good for an interview, NYCOM as well.
Here at PCOM, things are really getting rolling, so keep an eye out for a letter as well.
