i m preparing for jee-14,i study for atleast 5 hours but m still unable to score good marks in my classes test

NEVER TRY TO STUDY MORE GAIN YOUR MAXIMUM EFFORTS FROM THE SUMS YOU PRACTICE

GET THE MAXIMUM KNOWLEDGE FROM MORE SUM ITS NOT LIKE THAT THE MORE SUM YOU PRACTICE SO YOU GET GOOD MARKS. THE LESS YOU PRACTICE BUT TRY TO CLEAR MAXIMUM CONCEPTS FROM ONE SUM

FOR EG IF YOU HAVE DONE 1 SUM IN 2 MINS DONT GO TO DO THE ANOTHER SUMS SPEND ATLEAST 10 TO 15 MINS ON THAT SUM TRYING TO THAT SUM IN SOME OTHER WAYS AND IF YOU DONT GET THE WAY ASK YOU TEACHERS 

BUT DONT DO IN THE EXAMS AS YOU FINISH ONE SUM GET TO ANOTHER SUM AND AFTER THE EXAM COME HOME AND TRY WITH ANOTHER METHOD. AND TRY TO WRITE ON WHITE PAGES AND BOT THE RULED ONE  SO THAT YOU ARE ABLE TO KNOW THAT HOW MUCH ARE YOU CONCENTRATING........... IF THE HANDWRITING COMES STRAIGHT THEN YOU ARE PRESENT PHYSICALLY AND MENTALLY BOTH AND IF IT DOESNT COME THEN YOU ARE ONLY PHYSICALLT PRESENT HOPE IT HELPED YOU PLZZZZZZZZZZZZ APPROVE IF IT HELPED YOU..................
