Dear Brother,
         I hope this letter finds you in the best of health and spirits.you have been promoted to class 11th.It is time to for you to decide whether  you would like to study arts or science subjects.The world has progressed very much in the field of science.If we want to keep pace with it,we must keep our Knowledge of science up to date.Everyone should know the basics of science so i would advise you to study science subjects at least up to inter level.
    Convey my salam all at home.
