<p>If you mean literally 2400 vs. 2130 there is a vast difference. Something like 270 kids get 2400 vs. 35,000 with 2130 (or better) – superscoring aside. Factoring in superscoring changes the calculus somewhat, but you get the point. And as for HYPSM, their mean scores are way above 2130 for the unhooked.</p>
