Benedictine University  has a new way to help its alumni pay for their children's college tuitions. When alumni have two children who enroll at the Illinois university within a six-year period, the second child receives a 50 percent discount on tuition. A third child doesn't have to pay any tuition at all. Benedictine is not the first institution to offer a sibling scholarship. George Washington University  gives a discount to one sibling when another is enrolled at the same time.
