<p>Actually, if you play around with test numbers, you’ll see that ED doesn’t affect the overall admission rate that much and admission rate doesn’t really affect the selectivity ranking in USN as much as test scores and percentage of students in the top-tenth of their HS class, which are likely pulled down somewhat by ED.</p>
<p>So no, it is not about ranking. It is about having more students having NU as their first choice, as President Monty mentioned.</p>
