I would say, yes as NCERT covers 90% syllabus of questions of Biology as per the previous record so it would be better to get it done properly but apart from this I would also suggest you to follow some standard reference books as well to keep yourself in a safer side in case the pattern changes or the questions come from somewhere else.

Books which you can consider once you are done with NCERT -

Trueman's Biology Vol 1 and 2

Objective Biology by Dinesh

Pradeep Publication's Biology

GRB Bathla's Publication's for Biology

Hope this helps!!!!

NCERT books are very helpful to build your concept but only NCERT is not enough to complete your Syllabus. Some other books you need to prefer for NEET Preparation. Here are some books you can prefer.

Biology Books

• Trueman's Biology Vol 1 and 2
• Objective Biology by Dinesh
• Pradeep Publication's Biology

Physics Books

D C Pandey Objective Physics Concepts of Physics by H. C. Verma

Chemistry books

Physical Chemistry by O.P. Tandon

Good Luck!
