Money saving tips for boston college

So I’m thinking of attending boston college but the dorms are expensive which are about 14,000 a year. I’m wondering if I can move to an apartment and live with 10,000 a year. Are books expenses really 2,8000 for the year? Can I live with a three person dorm and save money or quadruple dorm? if so how much is does it cost? is it mandatory to live in a dorm or can i live in an apartment that’s from the campus?
