If one doesn't have sound understanding of elements, molecules, steriochemistry etc. then that person will not do good in the biological or chemical field. Similarly, if one doesn't have sound understanding of basic accounting principles, and basic knowledge of economics, then that person will not do good in business school. The foundation is very important. Take your time and rethink. Go to the library and borrow some intermediate level account and finance book. Read it for a week and ask yourself, does it excites you? I have heard that colleges put you in pre-mba courses if you are not from business background. This may increase the length of your MBA program. There are many MBA programs designed for different background student; however, if you want to go for accounting and finance, you need to start from the foundation courses. If not, human resources, marketing, general business are not that technical. If you can become the director of human resources, you make 114K !! This all depends on your self-confidence as well.
