Well, I have a week and a half until my first classes in my first year of college. My math class is multivariable calculus. However, while I aced Calculus in high school, I'm worried that college-level may be of a different caliber. So, I wanted to ask what should I know walking into that classroom? I know there's something called Stokes' Theorem, should I learn that? Is there anything? I was also wondering if you could give me some post-Calc II, pre-Calc III questions to refresh my mind. Any help would be greatly appreciated, as I'm slightly unnerved about college-level mathematics. I guess this isn't quite a homework question, is it?
