A story by the Associated Press points out that more than half of college students in the country have at least one credit card that is billed to them and about a quarter of these students have used their cards to pay tuition. A study by the American Council on Education found that many schools, particularly state institutions and community colleges, allow students to pay tuition with credit cards for convenience. But some schools do not approve of the practice, fearing it will steer students toward more expensive ways to borrow. Other colleges say the fees charged by credit card companies to process payments "aren't worth it."
