Elena,
I agree in certain courses, EC may have a role (however, should be small role). For me, in a medical education program, there is little wiggle room for students to be excused from demonstrating proficiency and competency in health matters and content that will ultimately be used in patient care settings. And in the work setting of most jobs there is no EC. That said, I know each instructor and institution has to decide what works best for them.
