Forget Harvard—one of the world's best undergraduate colleges is in Iran. Stanford University's Electrical Engineering Department were startled when a group of foreign students aced the notoriously difficult Ph.D. entrance exam, getting some of the highest scores ever. That the whiz kids weren't American wasn't odd; students from Asia and elsewhere excel in U.S. programs. The surprising thing, say Stanford administrators, is that the majority came from one country and one school: Sharif University of Science and Technology in Iran. Stanford has become a favorite destination of Sharif grads. Bruce A. Wooley, a former chair of the Electrical Engineering Department, has said that's because Sharif now has one of the best undergraduate electrical-engineering programs in the world. That's no small praise given its competition: MIT, Caltech and Stanford in the United States, Tsinghua in China and Cambridge in Britain.
