Hi D.gautham,

Ncert books highly conceptive so you need to concentrate more to grab the concept by ncert .

If you have really understood NCERT books completely line by line, gone through each and every word of it including the tables and reactions, all solved examples and all questions of the exercises then it will be sufficient to score around 200–240 depending on your accuracy.

But you need to practice more and more from different numerical books which you have need.

Hope it helps

All the best

Dear Aspirant,

You can score a maximum of upto 100 marks in chemistry ,if you study the NCERT book properly.but it is will be difficult for you to get more marks in physics and maths,if you only study the NCERT books.it is noticed that every year in mains,around 20 questions inclding maths and physics come from NCERT books .so,you can get a total score of around 170 ,if you only study the NCERT books.In order to get maximum score in maths and physics,you need to refer some other books other than NCERT books.

Hope this information is helpful to you.

thank you.
