Is AP Human, Pre-AP Biology, Pre-AP Chemistry, Pre-AP English 9, and Pre-Calc doable as a freshman?

Seems like you are three grade levels ahead in math (precalculus (= college algebra + trigonometry) is typically a 12th grade math course). Why would you need to take precalculus over two years if you are good enough in math to be three grade levels ahead?

Also, why two science courses and no foreign language course?
