I think I’ve seen something about this. NY Times? Washington Post? In the last day or two, certainly. It wasn’t about an MBA or GMAT, rather an undergraduate who was studying for a statistics exam.
The story sounded a little odd to some commentators as the guy was sweating over his books at 4 am and then got an A grade: most unlikely. It was also said that he was paying $18 an hour. Whether this means that he got a good deal, your MBA friend is getting a bad one or that they charge different amounts for different subjects I don’t know.
But the offshoring of education and tutoring will become more common, of that I am certain.
