The only one that comes to mind for me is the Pell Grant system, but I'm sure you already know about that one. It's been so long since I was in school and the only financial aid I ever got was from VA.
Good luck with your search and continued studies.

I looked in unexpected places for scholarships and found them. I got one from Lily Drug Corp (been taking their meds for a good decade or so), another from DAR, (I found a family member who I could link in from), and another from an organization that gives scholarships to Iroquois people.

What kind of degree are you going for? I know there are a lot of specific scholarships based upon what kind of degree you're going for. Like nursing they have a ton of full-rides from hospitals (I know, I'm going into nursing lol!)
