If you are unable to answer a question or are unsure of your response, consider referring to relevant textbooks, study materials, or online resources. This will help you gain a deeper understanding of the concepts and develop a broader knowledge base.

4. Discuss with peers and mentors:
Engage in discussions with your peers or mentors after solving the question paper. Share your answers and reasoning behind them. Listen to their perspectives and insights. This collaborative approach will expose you to different viewpoints and enhance your understanding of the subject.
