BU Financial Aid, EFC = 0, how am I supposed to pay?

<p>well my efc is 25000 and they only gave me 5500 in loans. got a letter saying bu will cost around 54000 total this year so is it possible that i can take a loan of 25000? im sorry this is kinda a stupid question but im clueless when it comes to paying/fin aid stuff.</p>
