They show both correlation with income, and success in college. The correlation with income and test results is quite possibly conflated with preparedness, since money provides more opportunities to succeed in school. Still isn't that the same thing? Folks who didn't have pre-college study opportunities might test less well. It doesn't mean they can't succeed in college. That's the point I think; we have to stop weighing environmental factors so highly, since they skew admissions toward wealthy applicants. Which is widely perceived as unfair.
