Following a timeline during UPSC preparation is crucial as it fosters discipline and ensures structured progress. Developing a clear timeline helps candidates to systematically cover the vast syllabus while accounting for adequate review and practice. A well-structured timeline allows for better time management, aiding in balancing study sessions with personal commitments. It also sets measurable goals, enhancing motivation as candidates track their achievements over time. Importantly, allocation of time for revision, test-taking, and improving weaker areas becomes manageable. Adhering to a timeline ultimately increases the likelihood of effective and comprehensive preparation.
