So they judged whether a student was qualified based on their school's "advertised requirements in terms of high school grade point average, SAT or ACT scores, letters of recommendation, and records of involvement in extracurricular activities." Specifically, they looked at students who failed every single test.

How can a recruited athlete fail at having an extracurricular activity? That doesn't even make sense. It's clear the author is just mixing and matching random studies with his preconceived conclusion.
