Integrating various subjects in UPSC preparation can be achieved through interdisciplinary strategies like thematic mapping, where candidates identify common threads across subjects. Creating mind maps helps visualize relationships between different topics. Additionally, relating subjects through case studies or current events encourages holistic understanding. Interlinking subjects boosts retention and aids in developing a comprehensive approach to problem-solving. Engaging with peer groups to discuss cross-disciplinary insights can stimulate complex thinking, enhancing one’s potential to tackle diverse questions in the UPSC examination.
