Tell you what, why don't you go look up the APRs for a few schools:
Stanford
Notre Dame
Air Force
Vanderbilt
Those are just a couple of schools off the top of my head who have high academic standards. How about you check out their APR and get back to me with your comment. The reason they don't have low APRs is because they are selective of the athletes they accept to their school and they do a good job of helping them to stay academically eligible and to graduate. High academic standards is not an excuse for low APR.
