<p>You have to remember that these kids are pre selected for Andover. If you read the Prep schools thread , you can get some idea how selective it is just to get into these top prep schools. And then you have the development, celeberity and legacy kids in much greater proportion than in most schools. Also any of the URMs who are there are heavily courted as the curriculum at these schools pretty much ensure that anyone who can cut it there can make it anywhere. About a quarter of the kids at these schools usually end up at non selective schools, I believe, instead of the other way around.</p>
