<p>Wow. The Natural Science GPA is absolutely terrifying (just a little over 3.1). It means that an average Princeton student majoring natural science will not even be competitive for any medical school. He or she must take a lot of humanity and social science classes to buff up his or her GPA. Alternatively, Princeton may have to screen for pre-med students to achieve over 90% admission. If I understand correctly, the table includes both undergrad students and undergrad alumni. A 3.1 GPA is going nowhere in medical school application, regardless which university you are from.</p>
