I've always been a bit of a math/science whiz. Back in Elementary school, I tested out high enough to be put into an advanced math path for junior High and High School - we were one year ahead of the 'normal' class.

When it came down to college entrance exams ACT and SAT, I placed in the '99 percentile' in math and sciences on both - which means it put me in the top one percent of college-bound students. That help tremendously with my nomination to the USAF academy, but didn't go there due to poor vision... My grades never reflected my abilities since I'm a lazy SOB that hates doing homework! I never handed any in! Same thing in college. If I don't 'get it', no amount of drudgery (homework) is going to change that. Either I get it, or I don't - ever. And what I do learn, I don't forget it - ever.

On standard IQ tests, I still test out to 140-145.
