<p>The phenomenon of pushing students into more advanced math courses than they are ready for may be quite common, due to the existence of two year calculus AB and BC sequences in many high schools. In theory, any student who is two years advanced in math should be easily capable of handling calculus BC in one year after completing precalculus. But some high schools force such students to take calculus AB over one year, then the rest of BC the next year, indicating that there is probably a considerable amount of inappropriate pushing going on in 7th grade.</p>
