Examination and challenge are essential part of ones life.Most of people does not take it seriously thats why they get depressed during examination.My experience says that we should not take it as challenge to get rid of depression even we shuld take it as festival.It is clear that mostly everyone is happy on festival.As we often see that when we try to remember something that we read in my book during exam but despite of trying alot we dont get to learn.As we come out from examination hall we get that topic is remembered to me surprisngly.So be happy during exams.
