Many questions in the GS papers incorporate themes related to organizations like the UN, WHO, and others that are essential for addressing global challenges such as climate change, health crises, and security issues. This understanding not only aids in the examination but also helps aspirants in interviews where questions on India's foreign policies and strategic initiatives are common. Mastery of these topics is vital for a comprehensive grasp of contemporary global issues.
