<p>You have plenty of time (over a year at least) to make friends in classes/dorm/clubs before you go on co-op. So your social life isn’t hindered in that way.</p>
<p>I will saw however that even the biggest partiers learn to hold off on Sunday night through Thursday night, because of work in the morning. That doesn’t mean parties shut down or anything, but the smarter people realize after a while that it really sucks commuting at 7 am with a hangover, so they party in moderation when work is tomorrow. That’s just what I’ve seen though-- obviously there are going to be people who aren’t affected by work at all and some who go to bed at 10 pm on the dot every night.</p>
