I was recently talking to a person who worked on a medical school board, and she told me that 3-4 hours a week should be the minimum for activities listed on the app. I have a few activities (e.g. mentoring, tutoring, etc.) that only occupy ~1 hour a week--should I just leave these off? (Although would it make a difference if I've been doing them consistently over a multiple-year period?) Thanks so much guys!
