<p>F.scottie, Yale’s system is not “virtually the exact same” as Harvard’s. Yale’s is far more comprehensive and all-encompassing, not to mention much, much, much more compact. There are huge differences between the two that can be best gleaned by a good 3-day overnight visit to each place. </p>
<p>As far as Princeton goes, if Yale’s and Harvard’s systems are Earth and Venus, so to speak, Princeton’s system is a small rock in the Oort Cloud.</p>
