Hi

Your profile suggest that you are a medicine aspirant so I am guessing that your question is with respect to Neet examination

Yes dear, NCERT Biology book is enough for you for your NEET examination and to score good marks like 350.

This is because,

in your NEET Biology section almost all the questions are from the concepts of NCERT. NCERT biology is not less than a bible for neet examination.

But yes just reading NCERT Biology will not help you, as in NEET examination questions are asked in the form of MCQs 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 at your fingertips.

You can go for a books like NCERT at your fingertips by mtg for Biology, it has topic wise questions it helps you in mastering NCERT in a systematic manner ,

To concentrate on your studies follow the below tips:-

*Don't keep your mobile near you while studying, as mobile is the biggest distraction while studying

*Make a routine, and try to give at least 8 hours or more to study , your routine should revolve around things i.e study, revise and practice . Routine will help you to eliminate procrastination

*Don't study a single subject for long hours as it makes you feel bored, keep changing the subject after every 2-3 hours

*Allow short breaks of 20 to 30 minutes in between your studies to refresh your mind

*You should practise at least 80 to 100 numericals and mcqs in Each chapter , practicing question helps your brain to be active other than reading only theory

*Solve previous year questions

*once you are done with the complete neet syllabus go through mock test papers .
