I will have my MBA in 6 weeks!
It will payoff for me (I work in Accounting/Finance). You basically need one now in order to qualify to sit for the CPA exam, which I will be doing this summer.
Before I started grad school, I had at least 3 years of work experience as well as a BA in Accounting.
Please be sure as to what your career aspirations are befoe starting ANY Masters program because grad school IS NOT cheap!
