Hello,

If you are asking about the reference books for class 11th for these subjects, then below I have listed some best books for each one of the subject.

Physics :

• Concepts of physics by HC Verma
• NCERT
• Dinesh Physics

Chemistry :

• NCERT
• OP Tonfon chemistry
• Pradeep's chemistry

Maths :

• RD Sharma Maths
• Cengage maths

If you are preparing for competitive exams, then you can join some test series. And the best thing is that, you should start solving previous year question papers from now onwards.

You can use you tube, as there are so many free channels, which will provide you complete course for 11th.

Hope it helps.
