This is from the poster @norcalguy a few years ago:

BTW: I’m in the admissions committee at my medical school. We do know that Brown is grade inflated. I wouldn’t say that makes Brown grades worthless but we focus more on MCAT scores with applicants from Brown. Hence, Brown’s acceptance rate to med school is only slightly better than Cornell’s (which is easily attributed to the fact the students at Brown are a bit stronger).
