<p>Since I probably know a little bit better how it really works, how about I tell you?</p>
<p>First off, the counseling staffs at both schools are second to none. Therefore usually a vast majority of students who go to Harvard or Princeton or Yale or Stanford or MIT apply early. </p>
<p>Also, the differences between top students at A and E can be very very very slim, making the process all the more a crap shoot, seeing as they really dont want to accept more than, say, 20 kids a year from each school. At least at Andover, students are not ranked and courses are not weighted. And much of the time it turns out that the early pool of applicants from A and E has a higher SAT average than the acceptees at the schools they are applying to!</p>
<p>So it turns out that the number of students going to each school mostly depends on how many were accepted. Last year at PA, Yale accepted the lowest percentage, followed by Harvard, followed by Princeton. This year, Princeton accepted an unprecedentedly low number of acceptees, followed by Harvard, while Yale accpeted the highest percentage.</p>
<p>Also, keep in mind that Harvard generally gets the most applications from each school, followed by Yale, followed by Princeton.</p>
