Candidates can enhance their ability to draw connections between different UPSC subjects by employing integrative learning strategies. This can involve creating interdisciplinary notes that link various topics from subjects like history, geography, and political science. Additionally, engaging in discussions with peers or mentors can help identify themes and patterns across subjects. Participating in mock discussions or group studies can also facilitate a deeper understanding. Regularly revisiting previous papers allows candidates to observe interconnections, thus enriching their overall preparation for the examination.
