Bluemagic, funny you should say that about abstract vs knowledge. I really thought DS would do better on the SAT because his teachers describe him as a highly astract thinker. If, as Howlerkarma DD says, the SAT questions are tricky, could that throw even abstract thinkers for a loop, backfire on them in a way? And the ACT was funny because the science portion is more of a reading test than science knowledge, although you should certainly have some school science to approach it.
Maybe DS should have taken more of the practice test sections! Maybe he took the tests too close together, just a month apart, and he was influenced by the one, and maybe even feeling cocky? (He'd found errors in the ACT prep test answer guide, but not in the SAT parts he'd done, maybe that threw him?)
