In the last month before the UPSC exams, candidates should prioritize revision and practice. This includes revisiting key concepts, summarizing subjects, and taking mock tests to assess strengths and weaknesses. Focusing on current affairs and integrating them into various topics can also enhance retention. Maintaining a balanced study routine and ensuring adequate rest is vital to avoid burnout. It’s advisable to tackle weaker subjects early while keeping stronger areas fresh. Healthy lifestyle practices, such as proper nutrition and exercise, should remain a priority to boost concentration.
