ATLANTA — Students at Georgia's public colleges and universities will see tuition increases this fall, after university system officials Tuesday backed increases including a 9 percent per semester boost at Georgia Tech and the University of Georgia. The majority of state-operated schools, including Georgia Southern University, will see a 2.5 percent increase for the fourth year in a row. Statewide, the Board of Regents of University System of Georgia has approved tuition increases each year since at least 2002.
