I guess when the NCAA Clearinghouse put a time-restraint of 4 years for players that changed the landscape. At one time players could take a fifth year or even longer and upgrade all their courses if they could not get through the NCAA Clearinghouse. You can no longer do that! After four years you can only upgrade a course...one single course and that's it. Therefore, you don't need prep to help you upgrade your courses...the work has to get done in four years or else you're JUCO bound.
