Hello Ayushi,

For scoring 300+ first of all NCERT should be read line by line and remembered by heart. You will get many common questions of you can do that. Sometimes, even 300-310 marks out of 360 are from NCERT only.

Other than that,

• Read at least one advanced book.
• Build your concepts. 
• Practice questions
• Revise and Re-revise. Remember regular revision is the key to maximize your score.

Hope this helps. You can contact for any further guidelines.
