Indigo - thanks for the advocacy speak! Gotta practice that. Makes sense.

Sunnyday - we are aware of the calculus trap. One plan is to take stretch algebra due to my son's age, then slow down and branch out to combinatorics / number theory, before moving on. I had not seen the second piece at all, and it was a great read. Definitely made us think more about asking for SSA to middle school math. Perhaps a flipped classroom where he does aops homework in school might work out better. Probably easier to get the school on board as well.
