To do well in a professional-school entrance exam you need to have majored in a related pre-professional field, right?  Wrong.  Liberal arts majors (broadly construed as science, social science, and humanities) do better than professional majors at the LSAT (for law school) and the GMAT (for business school).

Of course not every history major decides to go on to business school.  Those who do, however, do very well in the GMAT.  

Perhaps just as surprisingly, some liberal arts majors do better than business and other professional majors at overall career pay.

There's an interesting pattern, oft-noted.  Liberal arts majors (such as economics) might begin at a lower pay scale.  But over time they catch up and overcome their professionally-majored peers.
