According to the details of the M.B.L. program of the university of St. Gallen, there will be a one week negotiation course in Harvard. Has anyone made any experiences with this negotiation course?

This seems really to be a very good course offered by the Harvard University. But sometimes other couses may be a little bit overrated.

I am also interested in this course. But is it really true that the courses at the Harvard Law School are overrated? Have others made the same experience?
