Are you in goodstanding with your dad to live with him. Because if he is no longer paying tuition, I'd say go to community college, which is dirt fucking cheap, and work and save up for a university transfer. And if you apply for grants then those would probably cover the tuition.

The most useful classes are the upper division ones anyway and there are still good professors at community colleges and you can learn what you need to do.

You may be thinking "community college is for loser, etc" but its better than being in a shitload of debt.
