To ensure a well-rounded knowledge base for UPSC questions, aspirants should adopt a multi-faceted approach. They must regularly read newspapers to stay updated on current affairs, focus on core subjects like history, geography, and polity, and integrate interdisciplinary studies to fill knowledge gaps. Engaging in answer writing practice helps apply learned concepts, while taking comprehensive notes can clarify complex topics. Regularly revising content through mock tests enhances retention. Additionally, participation in discussions with peers or study groups broadens perspectives and reinforces understanding, ultimately preparing candidates for varied question formats.
