<p>When we were looking at which private HSs in Los Angeles area to apply to for 9th, I would look at each schools matriculation numbers. Some of the privates sent 0 or 1 % of their class to HYPS, most sent around 3%, but a few schools sent 20%. All of the private HSs seemed like wonderful places with lots of learning and activities. I bet the top students at each of the HSs were comparable with each other. So I presume this means that certain HSs either have a relationship with certain colleges or that some colleges have been happy with the performances of past students from a particular HS.</p>
