1. Yes.
2. There are not a lot of parties on campus. Large parties (with more than 20 or so people) have to be registered with the college and we only had two of them last semester, a third one got canceled due to lack of interest... There is not really a lot to do on campus, especially on weekends. Sometimes the college shows a movie or invites artists, but other than that you have to go off-campus for entertainment. What you do is completely up to you: you can go party at Swarthmore or Penn, you can watch a movie at the Bryn Mawr Film Institute, you can go into Philly or you can just hang out in the campus center or the dorms (you can even go to bed early - the dorms are usually quiet) or in the library finishing a paper. The most heavily used drug on campus is caffeine

Some people smoke, some people drink, but there is no big drug scene.
