<p>If you’re looking for something much more laid back (and you don’t mind a party scene), id say reed. read up on their whole idea of no grades.</p>
<p>if you want a more structured environment, id say chicago. also, if you’re looking for stuff with difficulty approaching or meeting the graduate level, chicago is your place. </p>
<p>i know chicago is very strong in all of the departments you mentioned, esp. in philosophy and math.</p>
