Not sure if it shows... but my inner-high-school is surfacing here and telling me that taking a class where I already knew all the material would be beyond boring!
Thanks to you and the others who replied.
I see your point, but if your children are in a public school that does not accommodate gifted children, and if you afterschool them at places such as Russian School of Math, already knowing most of the material in math class is the norm. The only difference with calculus is that there is a recognized exam to certify what has been learned outside of school.
