The public schools where we live do not have gifted programs and have little acceleration, although students can take AP Calculus in 11th grade. Our 12yo son, a middle child, is in 7th grade and is taking Algebra I in school and Algebra II at the Russian School of Math (RSM). He has scored in the 700s on the the math SAT. He wants to take precalculus at RSM over the summer.

The public schools will likely not deviate from the Algebra II/Geometry/Pre-calculus/Calculus sequence in grades 8-11. So I wonder what the benefit of accelerating him over the summer is. OTOH, we don't want to discourage him.
