I'm wondering if that is a drawback for those of us with grade accelerated children b/c they won't have hit the speed boost yet when they are dealing with high school material. Since my grade accelerated one had slower processing speed when she was tested at a younger age, any speed increase would be good, though. Hopefully it will happen before she's out of high school (assuming that this speed boost doesn't happen all in that 16-17 age range!).
