I am giving exam NSEJS exam. But i am reading in class 8 and NSEJS is a 10th based exam so please help me that from where i can start preparing for the exam

@ anirban 
just start up with the besics and go ahead .in this junior oympiad exam , they will ask you all the thing that u have studied from class 9-10 . 
so, if u are now in class 8 , u ave ample amount of time to prepare for it . "
just read the ncert and do s.chand , mtg , pradeep publishers questions , 
u can also take foundation live package from askiitian which are very helpfull . 
ALL THE BEST ..
