What parts of your profile do boarding schools look at?

By this question I mean: What percent of my grades are put into the fact or what percent of my ssat score is looked at.

So say if it was like a chart ( E X A M P L E )

10% makes up extracurricular activities
10% Community Service
30%grades
50% SSAT Score

Thank you

Well, I think the answer varies a lot for each boarding school (i.e. some boarding schools care more about community service than others)… What schools, specifically?

I mean schools such as Andover, Exeter or Lawrenceville
