Question

Mr. Davneet, I am a regular on your website. I have learned a lot from you, and I am very thankful. I recently saw your tips for the writing of board exams and among those tips, you mentioned that NCERT questions are very important as 6 questions are straight from the book and 3 are similar. That makes up 9 questions. What about the rest 21 questions? Where have those come from? What else do we students need to study other than the NCERT textbook?
