I'm currently in my undergrad at the University of Toronto which offers a service called "Credit/No Credit", it essentially acts the same way as Pass/Fail in some other universities. Basically, if you select "Credit/No Credit" for a course, your mark for the course will not be recorded on your academic record and you will receive the credit for the course, contingent on the fact that you pass the course. I have done some research and they recommend not doing it for a course that is a requirement for graduate schools but mentions nothing of medical schools. I have researched but found nothing on medical schools' views on selecting "Credit/No Credit". Do you think medical schools will frown upon it?
