I believe you just have 5-7 years to complete it depending on how strict your college is. As a former grad student I would not advise going over because you’re probably going to burn out, the cost is going to be pretty high unless state government or your company is paying for it and your holding a spot that could go to someone else. My humble opinion is to try to focus on a single concentration (I.e MIS, management, marketing) and to pursue that route a lot of it over rides with each other. If you don’t know what you want to do (again this is my opinion feel free to disregard it) then I would advise not pursuing an MBA cause ultimately it might be a waste of time and money if you’re paying out of pocket.
