Dear Aspirant,

for the preparation of NEET using NCERT textbooks to learn the basic concepts of each topic and then solving previous years question paper might be enough but is not sufficient. It is recommended that you use some of the other textbooks that are to be used, which are specifically for the preparation of NEET. This is recommended as it will be beneficial for you and in the long run help in your preparation and give you more in depth scope of understanding the topics and be thorough with solving the numericals.
