Bloomberg News and Southern California Public Radio report that billionaire entertainment mogul David Geffen is donating $100 million for full-ride scholarships for up to 33 medical students a year at UCLA, the school announced. The cost of medical school can exceed $300,000 for four years, and average debt for U.S. medical graduates was $170,000 in 2012, UCLA said. The gift makes Geffen the largest-ever donor to UCLA.
