Answer 2

Follow these tips to score highest marks in all subjects-

• Studying through NCERT is very important as most of the 3m and 5mquestions are asked in the board exam are based on ncert only.  
• NCERT Exemplar is important to practice as there are more chances of its questions being given in the exam than the reference books like RS Aggarwal.
• Solve questions from question bank for practising more chapterwise questions. Refer to Educart question bank as it provides a new typology of questions with important NCERT questions and PYQs.
• Practice sample papers (I think educart sample papers are most useful as the solutions are provided with detailed stepwise explanations along with the tricks applied to the tricky and conceptual questions ) as they are very important to understand the new typology of questions and get hold on to the objective section.
• Revise multiple times.

Hope this helps. All the best!
