KVPY examine the scientific aptitude of a student. So if you have an appetite for science you can also read other books which are a slightly higher level. Like for Chemistry-JD LEE etc. NCERT will built your foundations which may reach you to a great marks but its better to study more from book so that the unique thinking as well as the problem solving skills gets increased and this will not only help you in the written exam but it will also help you in the interview conducted.
