Package Deal: Purchasing 1) Schooling and 2) A Degree

Typically, students matriculate at a college (or other level of schooling) where they pay tuition and other payments in return for 1) the right to sit in a class and take exams leading to the issuance of a degree or diploma.

The seller (i.e., the college) has a conflictive interest in offering courses and writing, proctoring, and grading those same examinations.

Why doesn't the Federal Trade Commission rule that offering courses and testing as a package is a constraint on trade, as it has done with other package deals?
