Read about it here (from the Harvard Crimson,no less):

Harvard is a scam successfully perpetrated for centuries. Some years back when I was in the Reserves I was spending a night doing homework from grad school -- graduate business school at a state university. That night's work involved finance theory, which is based largely upon integral calculus and statistical modeling. A friend who was at the same time attending Harvard Business School asked me what I was doing. As I began to explain, he gave me a blank look, so I asked him what the math requirements for Harvard Business were. He said there were none. I then asked how Harvard Business classed were run. He replied that they just read cases for two years, discussed them, and then received an MBA. I couldn't believe it. Yet, Harvard continues to fool the world with the "value" of a Harvard MBA.
