Write a letter of advice to your younger brother who is about to appear in the examination
My dear Name,
I have just received your letter. You have written that your annual examination is at hand and that you are not satisfied with your preparation.
But I feel that you are a bit nervous. I am sure you will fare well because you have been regular in your studies. Do not lose heart and try to get rid of this phobia. Revise what you have already learnt. Be confident. Nothing can be achieved without courage. Get up early in the morning to study. Do not be panic. Take time to think over what you have studied. This will help you to remember well.
Do not lose heart. Pray to God daily. You shall feel strengthened. Write to me after your examination is over.
With best wishes.
Your elder brother,
