Are you forbidden from retaking the course/exam. If you get a C on your 3rd try, is that F still visible?
When I was at university you where in principle allowed to retake a course/exam as many times as you needed to pass.
The primary objective of students wanting to get into medical school is to get a high GPA, what specific courses they take and what they learned don't end up mattering at all. Very little of what they learn during the 4 years of undergrad will end up applying during medical school, residency, and their careers.
Or at least that was the case when I was at NYU.
If you failed with an F, then retook it and got an A, your grade is C.
Now, other schools don’t necessarily follow this model.
