No, college is not the ultimate preparation for flight school or to be a pilot but like everyone has said here, it prepares you to achieve your goals, self discipline yourself, gain some maturity, improve your writing skills, but most of all it opens your mind (hopefully) to alternative ways of thinking. Specifically, like FlyNavy said, it allows you to think at a higher level. If you have graduated college and are still asking this question, then you didn't get what you were supposed to have gotten out of it. "The stupid piece of paper" is just official proof that you did it; the real achievement is intangible. Just to echo Red2, you should be able to look back at your college years when you are done and be able to see things differently.
