<p>The link above only specifies what percent start out pre-med. It does not specify what portion of those drop out from 1st to last year. You mentioned that a friend of yours was told that 75-80% do not go onto a med school. This rate does not fit well with Stanford Daily article, the rate suggested by the study (rough estimate based on % of students who did not mention decreased interest in pre-med after 1st 2 years), or the rate among the small portion of students I knew, so it’s not clear me that your friend’s data was accurate. Was this same friend the source that stated 600-700 students or about 40% of the freshman class start out pre-med? If so, overestimating the number of entering pre-med students could explain the difference .</p>
