How far can just having a degree actually take you?

Everyone thinks that just because they have a degree that they are entitled to a job wherever they apply. But what a lot of people don't realize is that nine times out of ten if your applying for a job fresh out of college against someone who maybe went to one year of college or never went but has a some experience in what the company is looking for or if he spent the 4 years while you were in college learning programming languages or cisco based switches while you were learning about accounting or writing an english paper. I simply hate the fact that I come to college and waste two years of my life on these general education requirements that are so easy and simple that I didnt even have to do anything but show up for tests. I took the hardest classes possible in high school to "prepare" myself for college because I was told that was what was best for me. Then i get here and sure enough im sitting in a college algebra class which was easier than algebra 2 in high school then sitting in a calculus class which I learned in high school as well. Why does MTSU waste my time testing my knowledge on math when I can ace the classes that are "required". Please someone explain to me while im setting up a network will i need to know about how the body breaks down sugars, or if I am doing database work when will that accounting class come in handy? If i was being taught 4 years of relevant knowledge instead of being tested again on material I already knew to begin with then I would be better off when I graduate.
