Thanks Dude. This is actually one of DS's huge challenges. His ability is wildly out of whack with his achievement. His assessment showed dyslexia and dysgraphia.

We're trying to get the school to help with some accommodation even though his reading/math (and achievement scores) are "at grade level." So I'm hoping to show that ability reflected by a GAI of 178, matched with achievement at grade level and dyslexia/dysgraphia is represents something that should qualify for help, both with academics and the huge level of frustration he has.
