Question: Med School. According to the Association of American Medical Colleges, only 46% of medical school applicants were admitted to a medical school in the fall of 2006.5 Upon hearing this, the trustees of Striving College expressed concern that only 77 of the 180 students in their class of 2006 who applied to medical school were admitted.
