One of the good things about college is that in the beginning you take general education courses which reinforces the things that every well-educated person should know. It also gives the undecided student the time to select in what career he is really interested.
Your major does not have to be decided immediately. You can go into college as undecided; and as you work with your advisor, look at all the opportunities available to you. When choosing your major, be sure to have an end result in mind. Sometimes people major in things like Art History (Nothing against the subject because I love art also.), but they do not know what they are going to do with it after graduation. You like the subject, but what are the career opportunities. In today's world, it is important to have a end result in mind that will hold up in today's economy.
