I'm going to be majoring in Physics.

I'd like to brush up on some math skills before hand, as I want to be well prepared, especially since I've been away from math for a while. (Treat me as though I were a freshman coming out of HS, but with a lot of time off between HS and college. That is what I am, after all)

Any serious recommendations or suggestions would be well appreciated, especially from those of you who are in related fields/have experience.

I'm going to be spending all summer working on my math and physics preparation, regardless of whether I take summer courses or not. It is currently unlikely - the summer courses - but even then I'm willing to listen to suggestions. As far as my skill level, I want to start from the bottom, and make sure I learn things completely through, so I will humbly say that my math skills mediocre.

Thanks.
