<p>Stanford probably has a nice advantage over the Ivies in that it’s on the quarter system. Admit weekend is in late April, but that is still relatively early in Stanford’s spring quarter (which goes into early June), so the students may be less stressed by impending final exams and papers. </p>
<p>The Ivies in contrast have to host all the pre-frosh in mid-April, just a few weeks before the end of their spring semester. Lots more deadlines and such, for the hosts and rest of student body.</p>
