AP physics C assumes that the student is at least concurrently enrolled in calculus.
In college, introductory physics for physics majors tends to require more advanced math than AP physics C. For example, the course with E&M typically lists multivariable calculus as a corequisite.
In any case, the minimum high school prerequisites to major in physics in college are precalculus and high school physics. However, it appears that you will be well advanced of that already if you are ready to take AP physics C and have or will take calculus.
