Is there a secret for getting into Harvard?
Some people say Harvard is really difficult to get in, but once you get in, it's not any more difficult than any other decent college.
Many people say it's PASSION. Passion will be displayed in the organizations you were involved in (and were a leader in) high school. Your essay and interview should reflect your passion for a specific skill, activity, service project, etc.
Start a club in high school....They love stuff like that. Find a list of typical organizations in other schools and find a faculty member to sponosr it....works everytime....
