Dear aspirant,

It would be a difficult task to give notes on important lines of all the chapters of biology of class 11 as it would become very lengthy and the notes will be of more than 6000 characters and the app does not take more than 6000 characters. Also you can note download it as pdf or in other forms so you will have to find it again and again.

But a solution of this problem is there. You can download the NCERT Books, NCERT Solutions by Mukesh Kaushik from play store.

It provide you the contents in Hindi, English and Urdu. So, you can choose according to your needs.

Hope this helps!
