Harvard automatically sends every applicant a secondary, although the secondary is accompanied by a letter giving an idea of the characteristics of a competitive applicant. Naturally, Harvard screens for interview, with perhaps 15-20% invited. Early application is encouraged
From the 2003-2004 MSAR: For the 2001 entering class, there were 5,754 applicants. 780 were interviewed. 167 were in the first year class. More than 167 were probably offered places, how many more unknown, but not likely to be a large number.
For the 2001 class: mean GPA, 3.8; mean MCAT scores, VR-10.5, PS-11.9, BS-11.7; 51% women.
Harvard sends ALL acceptances out at the end of February. There is a wait-list.
