Medical school admissions committees are looking for students who will be able to keep up with the coursework. Most medical students agree that the amount of material required during the first two years of pre-clinical study is exponentially higher than the workload during undergraduate school. During the third and fourth (clinical) years, there are also physical and psychological demands made by very long hours, hard work and interaction with patients. Bottom line: It takes a highly motivated individual to pursue a career in medicine.
