Thanks everyone for all the replies! I do appreciate them.
McGurky, I'm a mentor who IRL does too many things. I suspect that the high school would figure that since I already graduated, I couldn't come back.

That's why I need to figure out a way to teach myself. I could take a community college class I suppose. Our cc classes are relatively expensive so I thought I'd give this a whirl.
It might take me a while, but I am going to try to learn this.
thanks again,
