<p>Is every weekend a 3 day weekend at penn? Are there no classes on fridays ever?</p>
<p>haha no. false. but its possible to arrange your schedule in such a manner…</p>
<p>columbia has no classes on friday (except lang classes sometimes) so you’re probably thinking of that :P</p>
<p>That’s only for Columbia’s Undergrads. Its graduate schools have classes even on Friday night from 8PM ~ 10PM (and I was in one of such classes this spring).</p>
