<p>Class rank is one thing, GPA is another. One can have a decent GPA, above 3.0 and still be ion the bottom half of the class, on the other hand, I knew someone whose GPA was 1.91 and was in the upper half of his class. I doubt either is very predictive of future success, especially since the actual studies done on the effect of GPA on later earnings find less than a 9% difference in income after 4 years out of college from those earning a 2.8 GPA vs. those earning a 3.8 GPA.</p>
