How does a pass/fail course for any undergraduate course be viewed before med schools so long as you take the course the second time around for a good grade?
Just an FYI, your situation is not very common and the answer is not too obvious either.
But, I can tell you this, your goal is not to get into medical school. It's to become a physician. They are not the same thing.
p/f wont matter other than possibly it being a minor question at interview. Perhaps a bit more if the course is a med school prereq
