I think Kaplan arranges these courses. I bought books from a guy who had taken such a course in LA. One cool thing about buying his used books was that 3 of the books (some of the most widely used review books) were signed personally by the authors. In other words, he was taught by top people in every subject.
He paid an arm and a leg, though. I think something like 7000 dollars for 6 weeks. He got a 242 and is now in a surgery residency in Baltimore, by the way.
Go to the Kaplan site and I'm sure they'll be more than willing to inform you about their classes.
Good luck
