Take an academically rigorous program of high school studies. Harvard expects its entering students to have finished four years each of high school English, math, science, and a single foreign language, as well as three years of history. At least one of the science courses must be at an advanced level. In addition to these subjects, Harvard recruits students who placed in the top 10 to 15 percent of their high school graduating classes.
Take the SAT or ACT standardized tests. Whichever test you take has to include the writing subtest. Harvard also expects its incoming students to take three SAT subject tests. They do not advise students to take these tests more than twice but they will consider a student's highest scores.
Prove that you are a distinguished student. This can be because of your academic achievement, your extracurricular experience or anything else that sets you apart from the pack. You can demonstrate this in your application essay and the teachers who write the reference letters about you should also emphasize what makes you uniquely qualified to go to Harvard.
Submit the common application and the Harvard Application Supplement online before December 1 of your senior year of high school. Do not attempt to submit the application electronically on weekday mornings between 9-10 Eastern Time because this is when Harvard performs routine server maintenance functions.
Arrange to visit Harvard and schedule an interview with the Admissions Department if possible. While this step is not an absolute requirement for admissions, if you acquit yourself well in an interview, the deans will be watching for your application. The Admissions and Visitor Center is located at Agassiz House, 5 James Street, Cambridge, Massachusetts 02138.
