<p>Last year 3810 students applied early, 697 were accepted. </p>
<p>Fifteen percent of the admitted students were sons or daughters of Princeton alumni. Twenty-five percent of the admitted students indicated they wanted to study engineering.</p>
<p>No stats on how many of the early applicants were children of alumni or applying for engineering, though. Essentially, you are as qualified as anyone else to be admitted to Princeton. Legacy will only help your application, but it is still a numbers game. You have to presume that there are at least five (or more) versions of you applying for the same spot, and it is hard to say what will tip you in. Legacy alone will probably not. However, again, you are obviously really competitive and I wish you luck! :)</p>
