Many faculty members at the University of North Carolina at Chapel Hill remain embarrassed by a recent scandal  involving "no show" classes in which students -- many of them athletes -- were receiving credit for courses that didn't require anything. Now UNC professors are being reminded of the scandal's impact. To prepare for an accreditor's visit, the university is trying to show that its classes are real. So administrators are making surprise inspections in class to make sure courses are actually taking place, The News & Observer  reported. Lewis Margolis, a faculty member in public health, said of the surprise visit campaign: "It was more than irritating. As I spoke to some colleagues about it, they looked at me and said, 'This is ridiculous. What the heck’s going on here?'"
