This question doesn’t make sense, because graduate students are admitted to a program, not a school. It makes sense to ask “What is the average GRE score for Harvard’s Molecular and Cellular Biology program?” or “What is the average GRE score for Harvard’s East Asian Languages and Literatures program?” but the average GRE score for Harvard’s graduate programs as a whole would not be useful to an applicant.</p>
<p>And the difference between being admitted to graduate school and being admitted to undergrad is that you want to portray yourself as a very lopsided future scholar in your specific discipline. Nobody cares if you’re well-rounded anymore, or if you participated in ten extracurriculars. They just care that you want to study and research one particular topic for the next half-decade of your life (or more), so they rely heavily on measures that reflect your potential as a scholar rather than just measures that reflect how “smart” you are.</p>
