So I sent out all my letters of recommendation today to AMCAS. I'm assuming it'll take about a week for the mail to get there. How long does it usually take for them to upload it into my application? I know AMCAS is pretty backed up in terms of handling mail so what's a reasonable estimate until they'll show up in my file and I can assign them to schools? I'm kinda worried because some of my secondaries have a 4 week deadline and I'm not sure if the letters will arrive in time...
