I am 15 years old and I am studying 11th standard, till my 10th standard I was studying in a cbse school, but now I have shifted to state board, in my new school all our studying well, the school where I studied before I used to get first mark, but now in my 11th standard when I compete with them, I am always loosing the battle, whenever I lose, I feel that I am cheating them, nowadays I am getting 15 th rank, due to these reasons I am getting mentally weak and I have also started to loose my confidence and also to think negatively. What are the ways by which I can improve my memory power to win in my competition.
