Hey guys! So this is my first year in division C, but I've competed in division B for 4 years. The national website doesn't have good information on this event, does anyone have any website suggestions or books I could get to study? Thanks!

So I was wondering if anyone had any tricks or sites they would be willing to share? Our first competition is in less then...
