Families flummoxed about what college will cost them have more information at their disposal than ever before. The Internet offers tuition data, advice on saving and borrowing, and explanations of financial aid. New online calculators let families estimate their bottom-line price at any college. But not all the information out there is easy to make sense of, and some of it's no good. A big push from the federal government to provide better consumer information has not created better-informed consumers. Families have more information than ever before, but no more clarity about the eventual cost of a diploma.
