Question

is ncert physics sufficient for 12th board​

Answer 1

Yes the study material of Ncert physics is sufficient for any exam.

Answer 2

Yes, NCERT is very important as most of the 3m and 5mquestions are asked in the board exam are based on ncert only. After going through ncert for 3 and 5m questions you need to grasp up the objective section and for that:

• Practise chapter-wise practice through a good question bank is essential to get hold of the concepts. For this, you can buy Educart question bank (Good because it provides a lot of new types of tricky and conceptual questions for the in-depth knowledge of a chapter along with important NCERT questions and PYQs).
• Do not forget to practice sample papers (I think educart sample papers are more useful as the solutions are provided with detailed stepwise explanations) as they are very important to understand the new typology of questions and get hold on to the objective section
