An effective study schedule for UPSC preparation consists of several key elements: a balanced mix of subjects, dedicated time slots for revision, and regular assessments. It should allow for flexibility to adapt to learning curves and incorporate breaks to prevent burnout. Targeted daily and weekly goals help maintain focus and motivation. Moreover, allocating time for current affairs updates and extra reading on optional subjects is essential. Ultimately, a well-structured study plan enhances productivity and ensures comprehensive coverage of the extensive syllabus.
