So, the consequence is that they would want to hold him back in math? I don't think the argument is this math can beat up that math. Seems the very issue we all face is trying to get the school to teach our kids at their level of learning. So the mano a mano is your son vs. whatever math achievement/placement tool they want to administer independent of his past historical instructional method(s). What if he had been homeschooled and you were interested in paying them money to educate him at his level?
