Students pursuing an MBA, or Master of Business Administration, should expect to commit two years of their time to it full-time; however, depending on the curriculum, some schools offer online and expedited courses that can be finished in as little as one year. Many business master's degree students, on the other hand, are working adults who can only attend classes part-time; in this situation, the program could take three to five years to complete. A master's degree, on the other hand, gets you closer to a doctorate and may allow you to transfer directly into a program like a PhD in marketing, finance, or management without further study.
