How do I get into Harvard (or any Ivy League School) as a freshman in high school, almost a sophomore?

(almost) Everyone will have great grades, AP classes, sports or traditional volunteer positions. If you do the same nothing about you will stand out. You're doing a great job by knowing what you want early. For the next 3 years you need nothing less than an A, you need to pick a cause related to the degree you want or cause you can relate to and devote time to creating an organization related to that. Keep taps on every dollar your raise or people who also volunteer because of you. You can pick homeless veteran or women's domestic violence center and you could use coupons to get free or nearly free items (solicit them from parents of other students/recycling center) to donate food to a shelter that supports them. You could sell muffins to raise money to send a foreign child to school. You could also pick a cause and get your entire class to support the cause.
