Is it worth it to skip class? After adjusting for room and board and other costs, it is $51.68 for an hour of class skipped. This metric assumes 16 weeks of class per semester at the University’s 15-credits-per-semester average. For out-of-state students skipping class costs $101.38 for every hour missed. International students spend $105.15, less than a $4 increase, for the same amount of time. Harley Wiltsey
