<p>I think that your son’s issue with the SAT I is probably exactly what you said – overthinking. My son had the same issue and also scored an 800 on the SAT II Math IIC without any prep. I do think, though, that looking at both his SAT I and SAT II give a different picture your son’s (now well-documented) potential. Where the first SAT I by itself didn’t demonstrate his mathematical abilities, even that taken with the 800 IIC would have shown something significant about it.</p>
