is there any possible way to add an activity after submitting amcas?? can i send an addendum to each individual school?? ive been able to mention it in the secondaries for a few schools, but i definitely wont be able to for all of them,and i feel like it's an activity that could potentially help me out...i wasn't sure if it counted when i was initially completing my amcas but now i realized i could have included it. any thoughts??
