How Much Financial Aid Should I Expect?

<p>I know there's no way to come up with the exact amount of financial aid I'll get, but I was wondering if any of the parents/prospective students could give me ballpark idea of how much I'll receive if my family has an EFC of around 27k. I know that's very much in the middle of the road since tuition is around 50k-55k. I read that USC is one of the top private universities in the country for financial aid, but I have no idea what to expect. Help!</p>
