Honestly I'd disagree with you (though I agree that the loan and schooling comment was definitely simplified). Not that they're dumb, but medical schools select more for hard workers who know how to memorize large quantities of information than anyone who's particularly bright among college graduates. Most medical students and doctors have a fairly poor understanding of math and statistics, a level of understanding of chemistry that's not particularly difficult, and a level of understanding of physics that doesn't go beyond a freshman level. Have you actually looked at MCAT study materials? Anyone who's majored in biology would know the material. What determines how well you do is the quality of your study habits. That said, hard work is usually what wins in the end in most fields, even those that do tend to attract the brightest.
