when i asked a rank holder he was a rank holder in Pe-1, Pe-2 and final(2nd rank ) , same question he told me start today . i will also say 

Start Today

one study one subjact then not think about other subjact

LIVE YOUR DREAM OF HAVING A RANK IN THE EXAM THROUGHOUT YOUR DAYS. BY "LIVING ONE'S DREAM", I MEAN TO SAY -  DON'T THINK ABOUT ANYTHING ELSE THAN HOW TO  FULFILL UR DREAM. IMAGINE THAT YOU HAVE ALREADY ACHEIVED WHAT YOU ALWAYS WANTED TO ACHIEVE. FEEL THAT JOY, THAT PASSION.

AS YOU DO THAT, YOU WILL FEEL THAT ALL YOUR ENERGY IS BEING DIVERTED AUTOMATICALLY IN THE FULFILLMENT OF YOUR MOST AWAITED DREAM. AND THAT'S WHAT WE CALL HAVING 100% CONCENTRATION, IN LAYMAN'S LANGUAGE.

BELEIVE ME, MY FRIEND, IT WORKS.

BESIDE THIS YOU SHOULD ANALYSE WHAT EXACTLY ARE THE EXPECTATIONS OF THE INSTITUTE, ETC..

ALL THE VERY BEST.

My friends also got rank in pe1 pe2 but they ayr not cleared finals still..............so past ranks can not be a valid and concreate base for the future performance............so work hard and dnt think abt future........hav a good study...............
