The AP program has become too driven by commercial interests. In an effort to attract more takers of its courses and exams, it deviated from its original mission. They’re too many of them. Many of them are too unchallenging. Their curricula are too regimented and too exam-oriented. More academically oriented colleges have constantly been tightening their AP credit policies to make them less meaningful (fewer credits, higher score barriers, etc). Some colleges don’t even give any credit for any scores on any AP course.
