I think I misinterpretted what you guys were saying. I agree that a lot of the stuff we learn in high school will never be applied in actual life. How many of us are seriously going to use things we learn from classes like Science and Math later on in our lives? Will we ever need to know what makes up a cell? Will we ever need to solve complicated math problems involving the Pascal's Triangle? Probably not.
What I was saying was, colleges look at your grades to detirmine whether or not you can apply. If you just completely brush aside academics, chances are, you aren't getting into a good college, or any college for that matter. I'm not saying that you need to get into college to be successful, but it definetly does help later on in life.
