Me learn math now

[BigPoppa]

I am thinking of going back to college (maybe a year from now).
I haven't taken a math class since Precalculus in HS over two decades ago.
If I do go back to college, I don't want to limit myself to non-mathy majors.
If I don't go back to college, I would still like to eliminate the gaping hole in my body of knowledge where math should be.

Right now I know nothing, and I don't want to get a rude awakening in a classroom.
So, I would like to teach myself math at least up through what is required of an Econ or non-Physics science major.

What books/self-study materials would you recommend?
Anything I should stay away from?
Any cool books to get me interested/edumacated on this stuff?
