Study groups are a great way to get to know people. And I would really encourage her to get to know people other than her teammates. Ask to borrow someone's notes as an icebreaker and then suggest a study session at the library (it must be about time for the first big round of tests for the semester). Find some interest groups (biking, service-oriented, religious groups, or whatever she's into). She clearly can't rely on the roommate and the team is not cohesive, so she will need to make her own fun.
