To effectively revise for the UPSC exam, it’s crucial to create a well-structured study plan that covers the entire syllabus. Identify key topics and allocate specific times for subjects, utilizing NCERT books for foundational concepts and standard reference materials for depth. Regularly practice previous years' papers and take mock tests to familiarize yourself with the exam pattern and improve time management. Note-taking and summarizing concepts in your own words can enhance retention.
Finally, maintain a balance between revision and rest to prevent burnout for optimal performance during the exam.
