@Riversider It is becoming progressively more common for people to take 1-2 gap years (or more) before applying! There are quite a few top schools now whose majority is made up of non-traditional students (UPenn is one off the top of my head). Additionally, it’s not usually recommended to list activities done during high school on the AMCAS unless the activity has been continued into college. Your most meaningful/significant clinical experiences should ideally be relatively more recent.
