The School of Continuing and Professional Studies of New York University in Manhattan began online classes in 1992. Its Virtual School has taught more than 10,000 students from across the United States and other countries. Last year，the school launched NYU Online. It offers NYU’s first online programs for a bachelor’s degree. Programs are offered in three areas：leadership and management，information systems management and social sciences. The classes are highly interactive，where students communicate with each other and their teachers. Some classes require students to log in at the same time 80 they can attend live lectures by a professor. Students can also ask questions and work together on team projects.
