How to pay for college with no financial aid OR help from parents?

I just wanted to apply to the UC schools because otherwise I would always wonder whether or not I would have been accepted and this way I’ll know. It doesn’t mean I’m planning on going there. It’s just always been a dream of mine I guess to go to a UC school because it would be a way for me to transition to living in California vs. just moving there and not knowing anyone or being established at all. It looks like I don’t have that option though lol.

And my FAFSA EFC is ~$50000
