<p>Look for schools with “house” systems: I know UChicago has a house system where people stay int eh same house all four years: they’re thrown in as freshman, and people tend to make friends with those living near them, rather than schools such as brown where people tend to make friends all over the place. House systems give you a “built-in” set of friends: I know my friend at UChic tended to do most of her socializing either within the house, or houses in her same dorm.</p>
