In the words of Yoda…“Careful you must be…debt is a path to the dark side.” OK, I made up some of that. But, you get what I’m saying 
The federal loan maximum is $27,000 for a 4 year degree. Your parents pay the rest, or co-sign it in the form of private loans. If you have to co-sign it, you can’t afford to go there. It’s that simple.
I don’t want to discourage you, but at the same time, a dream school will become a nightmare with a mountain of debt. I would definitely check out other private schools too. They vary considerably on how much financial aid they offer. For us, Vanderbilt and University of Chicago were more generous on their respective calculators.
