I recently purchased DMT and have been wondering about this. The authors give a LOT of weight to those talent search test results. If my fifth grader scored very well on the Explore 8th grade test, then she has managed to learn at least 8 years of math in 5 years. So she should be able to maintain that accelerated pace for the next 6 years? I don't know. It seems like a big jump from speeding through elementary school concepts to being able to speed through trigonometry. Does anyone have a long view on being able to maintain the acceleration through high school, or not? Is it dependent on LOG?
