Loans & savings, but mostly loans. I was turned down for student loans b/c my credit score (good enough to get a car loan on my own eight months prior) was no longer good enough in the current economic climate for me to get student loans. My parents offered to cosign w/ me, and that was enough to get me approved. I'm in my mid-thirties, so I definitely don't qualify for ParentPLUS or whatnot, and career-changer postbacc programs don't qualify as grad school, so no gradPLUS loans, either. Just good, old-fashioned private loans.
I know that more than one person who was accepted to our class ended up postponing because they couldn't get funding. I suspect this will be an increasingly common problem for students and programs alike.
