Relational thinking aids in tackling UPSC exam questions by enabling candidates to connect different concepts, historical events, and policies across disciplines. This cognitive approach fosters a comprehensive understanding of implications and interconnections, allowing for deeper analysis of issues. Candidates trained in relational thinking can draw upon examples from various subjects, thereby enriching their answers. This methodology enhances the ability to tackle complex questions, especially in essay-type responses and promotes a holistic grasp of the syllabus, improving performance in the exam.
