In life we have to design our question papers, we give the test and then we check our answer-sheets.
Mostly we find our self correct and our general score is about 90%.
Rest 10% are deducted due to shortage of time and other unavoidable reasons, which meant ideally our score should be approx. 100%.
we all live with our highscores and enjoy life.
But those who score less than 60% achieve targets.
