Once you submit secondaries, will schools start reviewing your app without letters? Do people usually send them in with the AMCAS? When is considered early to have your letters in?
My understanding is that LORs should be received around the same time as your secondary application. To my knowledge, both the secondary app and LORs must be received for your application to be considered complete and subsequently reviewed. However, I am only a premed myself so take what I say with a grain of salt. It may not be a universally true statement.
So when applicants are considered early, it is only based on having all 4 of those parts in? So if you submit your primary earlier than someone else, but they get their secondaries and LORs in before you, who would be reviewed first?
