My son is the same. He and his friends are all the high achievers in a rigorous school. But he would rather get a B in reading and writing (which he's currently getting) than take the extra time he's allowed in his 504 for dyslexia and dysgraphia. Like your son, he would have to go to a different room to take a test if he wanted extra time. I'm thrilled with his Bs, because he's come so far with his dyslexia and dysgraphia, but he would likely get As if he took the extra time and carefully read and tried to write with a bit of sophistication. But he's not interested yet.
