Georgia gives full, or close to full tuition for in-state students who attend their colleges through the Zell Miller program (3.7+ HS GPA & ACT26) , and partial tuition through their Hope scholarship (3.0 HS GPA) program. Thousands of students receive them (ZM), and even more get the Hope scholarship. All the student has to cover is room and board, plus a small amount (~$2K+ books) of tuition even at the most prestigious universities like Georgia Tech.
If other states had a similar programs we would not have a college cost crisis.
