How to use AP credit?

Hi, I am an incoming freshman in TMC, and i am beginning to plan my classes. I am currently undeclared, so for my first year I'm just trying to fulfill as many of my GEDs as I can. I want to use my AP exam scores in place of the natural science courses I need to take, but I don't know how.

I already sent my AP scores to the school, I just don't know how i can use them in place of classes.
