You are referring to pre-clinical which is one or one and a half years at the top medical schools. Pre-clinical is graded at the condensed curriculum pass/fail schools, it's just not relevant for residency. Shelf, Step and rotation performance is mostly what the residencies care about. Everyone does well in pre-clinical, it's massive general memorization. It's irrelevant for residency, or any part of being a doctor other than getting to the next step.
You would be better off picking your doctor by their MCAT score. That is the level of ridiculous here. IMHO.
