<p>What's the % of students that pay the full 50K price tag at top-tiers? 90%?</p>
<p>More like 40%-60% but it does differ between schools and all the colleges publish the percent receiving aid.</p>
<p>Also keep in mind that paying the full price tag does not mean that the student and his/her family actually have the cash to pay the full price. It simply means that the college determined that they are not eligible for financial aid. Many of these "full-pay" students are using private loans and scholarships in order to finance their education.</p>
