If the college has a pre-med committee that writes or does not write committee letters in support of medical school applicants (those not given committee letters are weeded out and told not to bother applying), the medical school admission rate may be more reflective of the pre-med committee’s threshold for writing a committee letter.
Being weeded out by the pre-med committee may not necessarily be a bad thing, even though it may feel bad. It means that a student with a poor chance of medical school admission will not have to waste effort, time, and money futilely applying to medical schools. However, some students may be willing to apply even with a lower chance of admission; such students may not want to attend a college where the pre-med committee has a higher threshold.
