Making the choice to go back to college as a mature adult can be a difficult decision. There are many factors to consider. Can you manage your marriage, your children, your job, your other commitments, and school? How much time can you devote to your studies? Why are you choosing to go back to school? Will the time and financial investment be worth the benefits that furthering your education will bring to you and your family? Are the sacrifices you will be making in time missed with your family and the financial burden it may place on your family worth the potential benefits?
Once you have considered all of these options and determined that going back to college is what is best for you and your family at this point there will be other things to consider. If your choice to further your education is based on a need for some continuing education or a higher degree to advance in your career, you may need to do some research to ensure that you are taking the appropriate coursework to reach your goals in the shortest period of time. You definitely do not want to be wasting any time or money on this venture.
However, if you have chosen to attend college in pursuit of a new career, you may have more flexibility in choosing classes and deciding on the appropriate amount of time to spend working towards your new degree or career goals. Your options will most likely be limited more by your financial situation or family commitments than time constraints.
