<p>This is not fact, this is your assumption. There are so many inconsistencies that betray your assumption. Certainly, yes, people who are perfect tend to do better than those who are not perfect. But the trend among the imperfect seems to tend toward an incomplete mastery of the faculties of the mind, tending more toward either aptitude or memory.

The idiosyncrasies of countless strong-GPA individuals are simply staggering, they are almost savant-like in the way that certain faculties dominate their consciousness, especially those with low IQs.</p>
