Ah school. That were the times. I always had the habit to calculate the minimum grade I had to achieve in a test to pass the class before the test. Then I would learn exactly the necessary minimum necessary to pass. Only once I did a small miscalculation - with the result that I spent 14 instead of the normal 13 years at school.
