hum. I dunno about those rumors. I am still fairly confident that when you hit that little "send" button on the AMCAS, the AAMC emails an electronic file containing all your AMCAS data, along with a hard-copy paper file to each school on your list.
AMCAS sending out information is more sensible than schools downloading. Think about it; the schools wouldn't download everyone's info, only the people who designate which schools they want. Also, the schools would have to hit download like every day, to make sure they catch people who add more schools to the list that they want the info sent to... and finally, I don't think $30 per school justifies an electronic-only file submission service. That is simply unacceptable. It is costly because they also produce a paper file and mail that out as well, along with the administrative milieu that maintains this transmission system (personell overseeing the operation, support teams, etc.) they can justify that cost...
anyway. rest assured when you hit "submit", the schools will get it shortly, one way or another.
