I agree 30,000 is in the future. With that approx. scenario (and a class size of 1,350):</p>
<p>If UChicago had 30,000 applicants and 50% yield rate, admit rate would be: 9.0% (2700 / 30000)
If UChicago had 31,000 applicants and 50% yield rate, admit rate would be: 8.7% (2700 / 31000)</p>
<p>Correction: WHEN!</p>
