Knowledge of international organizations benefits UPSC aspirants by equipping them with insights into global governance, sustainable development goals, and multilateral diplomacy. Understanding the role and functions of key entities like the UN and WTO enables candidates to relate current events to institutional frameworks. This knowledge not only enriches their answers in exams but also prepares them for real-world scenarios they might encounter as civil servants. Furthermore, being familiar with various treaties and agreements can help aspirants analyze India's position in a global context effectively.
