@Malina_Misa: @AuraObscura is correct. I’m a bio major (specifically, bio with a concentration in neurobio), and I’m lucky enough sitting at one of the top US MD-granting institutions, so nobody held it against me. Adcoms do not sit around the table saying, “I really like this one, she’s a 4.0, 43 MCAT (or I guess it would be 525 MCAT now), 500+ hours volunteering, wide range of specialties and primary care shadowing, 3000+ hours of research, 3 first author pubs in Nature, graduated magna cum laude…but oh darn, she’s a bio major, so I’m not sure that we should accept her.”
Major in what you love. See my post here for why: http://talk.collegeconfidential.com/science-majors/1812121-specialized-biology-majors-are-for-the-birds-p2.html
And recognize that many people who think they want to be physicians will end up never completing the pre-med track. At Stanford, there was a 50% attrition rate; I hear from my med school friends that it was even worse at some other institutions.
