After all this is your life, you make it most beautiful or destroy it. It will eventually effect you alone. So be with yourself, ask honestly and you will find the answers to your query. You are likely to know that failure and success is matter of life and death to your examination performance. If you pass and come to the expectations who matter to you will make you feel relieved.
Life is very kind.
So is God. It has evenly spread the flowers and thorns for all of us. No one has come to earth who does not go without getting pain. Similarly no one has been to this planet who has only seen misery. If you think in either way you are making a wrong judgment.
