What kind of calculus is DE calculus?
A college calculus course may be regular calculus (suitable for math, physics, engineering majors) or business calculus (suitable for business majors). Business calculus is easier and covers less material with less difficult problems. However, it may not be accepted by as many majors that require calculus.
Calculus AB covers similar material as the first semester plus maybe a bit more of regular calculus, while calculus BC covers the first and second semester of regular calculus.
Still not sure why you are worried about calculus in 11th grade after completing honors precalculus in 10th grade (two grade levels ahead, implying that you are a strong student in math).
