Hi Rahul

Yes NCERT Biology is enough for getting good score like 320 + or more.

This is because almost 95% or more of the questions in NEET Biology are from the concepts of NCERT.

But yes only reading NCERT Biology is not going to help you in your examination as questions in NEET examination are in the form of MCQ so you need to practice lots of MCQs in order to score good marks, and you need to master NCERT to the level that it is only your fingertips.

You can go for a book called NCERT at your fingertips by mtg for Biology, it has topic wise questions it helps you in mastering NCERT in a systematic manner . Also, Biology is all about understanding concepts and then remembering and memorizing facts so you should go at least twice Or thrice through NCERT Biology  book to master it
