I think I responded to that thread, and I see your point. Rereading the thread now, I see that I was responding to someone who was asking about level 5 kids condensing all of elementary school into the space of a year or two, and then being ready for college around age 11-12. That would be the case for us in terms of elementary school, and very possibly the case for the college issue. I do not see our son being ready for graduate school at 11 or 12. But, I don't doubt that such children exist.
Just as there is a major difference between a 130 child and a 150 child (to use the IQ standard), there must be a major difference between a 150 child and a 180-200 child. And, as you say, it is just as unfair to lump those groups together. Their capabilities at the same age will be markedly different. I completely agree with you.
One question: I wanted to clarify something about what you said. Are you saying that it is an EG child who would be ready for college at 11 (as opposed to a PG child, who would be ready several years earlier)? I'm trying to be sure I understand the labels involved.
