Aspirants can best manage their time during the UPSC Mains by creating a detailed study calendar that includes daily goals and time allocations for each subject. Practicing under timed conditions is crucial to simulate the pressure of the exam environment. Prioritizing difficult subjects or topics during high-energy hours can enhance focus and efficiency. Incorporating short breaks and consistent review sessions can prevent burnout and improve retention. Efficient time management ultimately ensures comprehensive coverage of the syllabus and helps candidates develop the stamina necessary for long examination hours.
