In my high school, our top ten was mostly SJs who had all taken AP/college-level math courses and were passing them with flying colors. Their knack for detail is ALWAYS appreciated in the math/chemistry/physics area, and add to that their pragmatism and unyielding hard work... Viola! Math machines.
Actually, acing difficult math courses may not have anything to do with type but with just pure intelligence. I did notice though that our top ten was mostly NT/SJ with an ESTP (the vale and a ruthless SOB) and an INFJ (#10 and the only chick). It really couldn't have been any more stereotypical
