The basis of the college education is to give you a little information about a lot of things and a lot of information about one thing. You take a bunch of unrelated course because the information is general knowledge that most college educated people should have. It also helps people decide what they want to do. I have many friends who went to college with what they thought they wanted to be only to be in school for 6-7 years because they changed majors. You may know what you want to do, but many think they do and are wrong. Once you are through the entry level course you will start on your major.
