Once the Spring Semester starts up, I'll be applying to become a mathematics tutor at my community college. I have good blessings for it from my Calculus Professor. I'll essentially be tutoring from basic developmental maths through precalculus and Calculus I. I've got the calculus down rather well, I've been reviewing it over the break to kind of cement it in my head, and I have a thorough grasp on what's taught in the class so I think it will be easy for me to tutor that. The others may be a bit more difficult for me I think, though, not for lack of skill in the subject but simply because it's been a while since I've taken precalculus and the basic maths. So I've been refreshing myself with Khan academy, and been practicing basic algebra along with my calculus stuff every day. Outside of Khan academy, what would you guys recommend as resources to make sure my knowledge is mostly complete and I have the ability to tutor people in the basic developmental maths and precalculus as well as Calculus?
