You will probably get a chance to "test out" of some of the more elementary college classes. If you get a high enough score, they put you right into more complicated classes. This is not necessarily good, because if it is too complicated you can be more or less lost from day one.
From personal experience, all classes of math were my favorites in high school. I sailed through the preliminary college test like a breeze, so didn't have to take Math I and Math II. They put me right into College Algebra. I was lost right from the get go. In high school algebra, most problems have a definite answer. Not so in college algebra. It seemed most answers were of an abstract nature, as was the instructor at the time. He was pretty abstract, and though he seemed to know his subject matter, it was difficult for him to pass the learning on to his students.
If your goals of the moment don't seem as desirable on down the line, don't be afraid to shoot for a different star. If another major looks like it has more going for it--go for it. If college seems a complete waste of time, don't be afraid to go to a trade school instead or even sit out a year, get a job, and test the water in the cold hard real world.
Stay honest with yourself. If you can look at the man in the mirror and consider him a man of integrity, you can sleep well at night. Keep your promises, and don't make any promises you can't keep. Have fun, live to learn, and learn to live. Happiness is the journey, not the destination. Go for it, and keep us Bull Sessionaires posted. Bon Voyage.
