FILE - In this March 13, 2012, file photo, University of Illinois students study on the Quad on campus in Urbana, Ill. The Illinois law that locks in tuition rates for in-state students appears to have the unintended effect of driving up tuition and fees for some students, according to a pair of studies from University of Illinois researchers. The law guarantees that a student starting as a freshman at a state university in Illinois will pay the same tuition rate for four years. (Robert K. O'Daniell/The News-Gazette via AP, File) less
