It is pretty easy to swap rooms, especially at the beginning of the year. I know some people who didn't get along with their roommates and all of them switched to live somewhere else. Plus, you never know; you might get lucky. I absolutely love my roommate this year, and we just got paired together by chance. She is definitely one of my best friends at school. The best advice I can give you is to talk over the summer once you get your assignment. By the time I got to school, I already felt like I knew my roommate. Then, find at least one thing you can bond over. My roommate and I always watched the Daily Show together at the beginning of the year, and it gave us something to talk about. Good luck
