Revision for General Studies differs from optional subjects because it requires a broader understanding of diverse topics, focusing on interconnections among subjects. For General Studies, candidates should emphasize current affairs and foundational concepts found in NCERTs and standard reference books. On the other hand, revision for optional subjects demands in-depth focus on advanced topics and theories, often requiring comprehensive understanding of theories and critical analysis. Tailoring revision strategies to the specific demands of each paper ensures optimal retention and performance in the exams.
