Hello,

on first priority, read NCERT line by line. Chapter having bold words and side notes is important so keep high focus on it.

on 2nd priority Follow your state board book i.e. academic book for reference.

on 3rd solve previous year question papers of NEET, AIIMS and other entrance exams which will give you good question bank and you will know how question is asked in entrance exam.

on 4rth step, appear mock tests and check your performance. Improve your weak sections.

Learning is not about reading books only. You have to measure yourself to know how much you understood and how were you don't get the concept.

Hope it helps!
