MEDIA, Pa. (AP) — Penn State is keeping in-state college tuition flat across the sprawling university system for a second year and for the third time in five years. The school’s board voted Thursday for a plan that will maintain full-time tuition for lower-division Pennsylvania resident undergraduates at its main campus at about $17,400 annually. Out-of-state college students at the University Park flagship will have to pay $660 a year in additional tuition.
