My scores come out Sept 21st. If I want my schools to receive the secondaries in before my MCAT so that my MCAT is all theyre waiting for, whats the least amount of weeks in advance can I wait before sending them?
You can send your secondaries in whenever you want (read: now) and they won't even look at them until they have your MCAT score. So I say send them in now so once they see your MCAT, they can make a decision ASAP (which the earlier, the better)
Each school is probably different with the time between secondary submitted to secondary looked at.
I agree with the above posters. Submit the secondaries ASAP so that everything is there and as soon as the MCAT score arrives your files will be complete. Keep in mind that schools are busy and your secondaries/MCAT scores aren't always marked as received right away and reviewed. Try to get as much in as possible now to reduce delays after the MCAT score is released.
