NEW YORK (AP) - When those college tuition bills come in, be prepared for sticker shock. The average tuition at a four-year public university climbed 15 percent between 2008 and 2010, fueled by state budget cuts for higher education and increases of 40 percent and more at universities in states like Georgia, Arizona and California. The U.S. Department of Education's annual look at college affordability also found significant price increases at the nation's private universities, including at for-profit institutions, where the net price for some schools is now twice as high as Harvard.
