@Reddyparent3 my bad if I wasn’t clear, I was specifically referring to premed reqs. As to other courses taken P/F, some schools may not care if there some. But which schools care, do not care? How many P/Fs are too many for any one school, for any one adcom to question as to whether an applicant can handle the academics? I don’t know, you don’t know and it’s not published info. At least academically, grades (specifically an A) tend to offer a clearer picture of an applicant’s ability than the vagueness of P/Fs. You may disagree and that’s okay.
