<p>I think that they look at past hs grads in your school only if your school sends a large number of apps to that college, or if very few people have ever applied to that college. If very few people from your high school has ever applied to a specific college, (u'll be surprised, ask your college counselors in hs) u will have a great chance to be accepted. If your hs always has an X number of students going to a certain college, then of course u know they do have a quota for your school.</p>
