I am not able to score well.How to enhance my level of preparation for JEE??

@ pranjal 
u need to do the following things to enhance the prep for jee . 
1- make a proper time table and always stick to it . 
2- do practice as much ques as u can but dnt loose time in practicing the same level ques , just increase the toughness . 
3- clear your besics , thats most imp for jee prep . 
4- in everyday level take a mock test of what u have learnt on daily besis , so, that u will not forget anything 
5- make sure u complete all syllabus before a month of jee mains exam . 
6- in the last 3 months , start practicing the all india test series mock test paper . 
and analyse your rank everytime . 
HOPE IT CLEARS 
ALL THE BEST ..
