As a NEET aspirants should my preparation be more on NCERT base? Can you please give an idea to get more cautious about the preparation needed to crack the NEET 2020

NCERT books are the base on which the 12th board exams are conducted. Now to convert that entire NCERT into 45 MCQs to test the subject knowledge and understanding of the Candidate's adaptability of subject matter, NCERT is not enough. That is the reason, questions are also asked out of NCERT. To complement the  questions asked and to be ready with the kind of questions thrown at you, it is always good to keep yourself trained with the help of more books.
