Opinion
Harvard, Stanford, Duke and Oxford universities, along with the Massachusetts Institute of Technology, may all be considered among the most exclusive universities in the world, but you no longer have to be a valedictorian, an All-American athlete, the founder of a successful not-for-profit or even a high-school graduate to attend one of their classes.
Harvard is the most recent addition to the small but growing group of prestigious universities that are making some form of their course materials available to the general public, online and free of charge.
