I have only done cbse past year paper questions,is it sufficient to get 90% in cbse 12,if not then give procedure to do

HI MIHIR

IF YOU HAVE DONE THESE WILL UNDERSTANDING THEN YES YOU CAN GET A GOOD SCORE. BUT TO GET 90% + MARKS I THINK YOU HAVE TO DO NCERT EXERCISES ALONG WITH IT. IF YU HAVE DONE NCERT EXERCISES ALONG WITH CBSE LAST 10 YEAR PAPERS THEN YES IT WILL BE ENOUGH TO GET 90% + MARKS

THANKS

PLEASE LET ME KNOW IF YOU HAVE STILL SOME DOUBT

KEEP POSTING:}
