As someone who was accepted and got to see their financial aid package, I have to mention that it's extremely generous as well. They don't just cover room and board and tuition, there's an understanding that you're poorer than your peers at the university so there's general spending money, money to buy winter clothes, money to fly home 2x-3x a year.

This is a rounding error for Harvard, but I didn't realize how limiting not having that would be at the school I ended up going to (which only covered tuition and most of room and board).
