The Georgia University System's board approved the rates at a meeting Tuesday. In-state students at Georgia Tech will see the biggest increase, up $405 per semester. That's a 9 percent increase.

University of Georgia tuition is going up by the same rate, an additional $387 per semester.

Georgia State University and Georgia Regents University will see a 5.5 percent increase, around $220.

Students at six other schools will see increases ranging from 3 to 9 percent.
