While that may seem like an aggressive pace for high school, note that college precalculus and introductory statistics courses are one semester each. In college, these are typically taken by the weaker-in-math students at the college. In contrast, the high school course in question will have the stronger-in-math students (including the OP who is two grade levels ahead in math), since it is the highest honors course. So it should not be that steep a hill to climb for the students in that course.
