Integrated studies play a crucial role in preparing for the UPSC Civil Services as they facilitate a holistic understanding of topics. By connecting different subjects like history, political science, and economics, candidates can grasp interlinked concepts and apply them to real-world scenarios. This approach enhances critical thinking and problem-solving skills, essential for both the preliminary and mains exams. Furthermore, integrated studies help candidates in answering essay questions and engaging in policy discussions effectively during interviews.
