If you have an undergraduate business degree, we at Entablature suggest that you consider pursuing a graduate program in another field, such as international relations, law, economics, journalism or public policy. This will arm you with knowledge and skills that will complement your business training, thus rendering you a more erudite business professional. If you do have an undergraduate degree in business and nevertheless want to do graduate work in the field no matter what, then we strongly suggest that you think about a specialty that you want to pursue, such as business & economics analysis, finance, international business, organizational behavior, strategy, entrepreneurship or econometrics.

We at Entablature recommend as much because - in this increasingly complex world - it helps to know a lot about a few things in addition to knowing something about a lot of things. Moreover, many of the basic courses in business school may be redundant to someone with an undergraduate business degree.  

You will want to extract as much from the MBA experience as possible. This means stretching your intellectual horizon and broadening your skill set. Push yourself, even it means tackling a difficult concentration that you find interesting.
