So on the AMCAS website, I remembered it says that your application will not be sent out until the 25th, so does it really put you at a disadvantage (at all) for rolling admissions whether or not you submit today or in two weeks?
The longer you wait to submit, the more the AAMC seems to get backed up and it takes longer to verify. Submit as soon as everything's done and accurate, IMO.
We're still pretty early on, but check out the ACMAS verification thread.
What Geekchick said. No, it doesn't matter, but the longer you wait the longer verification takes. If you wait too long you won't be verified until after the 25th.
