Hello Ami Bhatnagar.

I would like to inform you that questions asked in KVPY are completely different from the standards of questions asked in JEE MAINS or some othe competitive exams.

The question are mostly based on simple concepts and you need to apply you logic then and there and are just like aptitude questions. Thus NCERT books are more than enough. However i would suggest that you practice from some question banks too.
