Your GPA matter (but you still have time to bring it up). AP scores, SAT, and ACT scores will probably matter more. I don't know if you've taken AP classes, but you should certainly consider it if for next year if you haven't.

For SAT and ACT, you should have taken your first of those by the end of this year and again sometime around the beginning of the next before college applications are due. They will matter a TON as far as both getting in to college and how much you pay.

As for college, I'll admit it is not for everyone. It's not worth much if you don't put some effort into it (and get a 3.0 or better really).

Regional captain salaries certain can support a family, but if you want to get into the majors you will want a degree. If you don't get a degree, get lots of military experience.
