Aspirants can build a comprehensive resource bank for UPSC preparation by gathering a variety of materials, such as books, articles, and online resources. Maintaining a categorized collection by subject or topic can enhance accessibility. Regularly updating this bank with current affairs and recent publications is crucial for staying relevant. Candidates should also utilize government reports, notifications, and previous year’s papers to familiarize themselves with exam patterns. A diverse and well-organized resource bank supports a holistic understanding of the syllabus.
