Balancing depth and breadth in UPSC studies is crucial for success. To achieve this, candidates should prioritize creating a structured study schedule that allocates time for both core subjects and current affairs. Focusing on key topics in detail ensures a solid grasp, while regularly reviewing general knowledge helps maintain a broader understanding. Using mind maps can aid in connecting various subjects, enabling a comprehensive overview. Regular practice with previous year question papers and mock tests can help gauge knowledge depth while ensuring coverage across the syllabus. Finally, revisiting complex topics periodically can enhance retention.
