Be prepared to work. You won't slide by, even if you are naturally smart. Focus on your work, even though the school isn't big on parties, so I wouldn't say it's terribly difficult to stay focused at Saint Xavier. Don't be afraid to ask for help, because you will need it. Bring that pride down a few notches. Wait on buying books. And if you do, chances are you'll find them much much cheaper online than in the bookstore. If you're a nerd, the school is perfect for you. If you're more the party type, and you like big football games and big crowds of people at school events, be prepared to have to travel to other campuses (if you have friends at the bigger schools like U of I, UIC, or NIU) because everything here is VERY chill. Almost too chill. Especially on the weekends.
