Candidates can approach intersubject linking in their UPSC studies by identifying thematic connections among different subjects, such as linkages between history and polity, or economics and geography. This integrated approach fosters a comprehensive understanding of complex issues and helps in crafting well-rounded answers. Utilizing mind maps or comparative tables can assist in visualizing these connections. Building a holistic view of topics enhances critical thinking skills and allows candidates to respond to interdisciplinary questions more effectively.
