If I submit my primary application via AMCAS for ONLY ONE SCHOOL for the purposes of getting my application processed and pay the amount due, BUT THEN FILE my FAP and get approved later on, will I still have 20 primary application fees waived via the FAP? Essentially I'll pay for the first school, but would like to have the fee waiver kick in for the future schools that I apply to after receiving my MCAT score. I imagine this is how it works since they say benefits are not retroactive, so I'll just pay for the one school to process my application in the mean time, and then use the benefits for the other 20 schools I plan on applying to. Thank you.
