^^ That’s all well and good, but you can achieve that goal by attending any number of strong undergraduate universities, doing well in your pre-med studies and scoring a top MCAT score. So, why Harvard? What does Harvard offer you that cannot be obtained at say Yale, Princeton, Stanford, MIT, Amherst, Pomona, Georgetown, Duke, Williams etc?
FWIW: As your college GPA and MCAT score matter the most for top medical schools, you might actually be in a better position for med school by attending a less prestigious undergraduate school. Have you read this article: http://www.thecrimson.com/article/2013/9/26/the-real-premed-requirements/
