When we send in update letters and get email confirmations, does that necessarily mean they've been added? I know Penn is the only school that actually lists all your updates so we can be sure what's added and what's not. Since everything is electronic these days and most schools just download what AMCAS has for us, how will they make the update letters available to our reviewers? I'm a little worried because Baylor sent me an email saying my update was received and added to my file. When I called, the lady said she couldn't find the letter and they usually don't add updates to files unless someone has been interviewed... This makes me think schools' confirmation email doesn't necessary mean they've actually added the letter to our files. Anyone with more experience on this?
