school is to help you grow up. transition into real life, from childhood to adolescence to adult hood.
its not all about passing. if all you care about is the letter grade, then it will be, but if you go to school with a desire to learn how to think then you will benefit far more than if you go with the desire to earn an A.
Everyone is a lifelong learner, school just teaches you how to become an expert learner.
