<p>Depends on which Ivy. According to 2011 National University rankings, Chicago is lower than UPenn, Harvard, Yale, Columbia, and Princeton, tied with Dartmouth, and higher than Cornell or Brown. This is, however, truly nitpicking- the true differences in admissions data are quite small. Still, even these small differences are significant- Harvard, Yale, and Princeton are all definitely a level above Chicago in both selectivity and prestige.</p>
