Undergrad/premed: live with family, have 100% 24/7 familial support of your education, living at home with all of your essential basic living needs taken care of. Residency: move to a different location away from family, no longer living in a dormitory environment with the expectations associated with being a student but are now a real adult making your way in the world. Suddenly you have to make the whole package work on your own without laundry/cooking/mental health/financial support. Now you can no longer put 100% of yourself into your studies, but instead can only manage the 60 or 70% that most people can muster when they have to actually maintain their physical existence while also meeting their professional expectations.
