Aspirants can identify their strengths and weaknesses during their UPSC journey through regular self-assessment and feedback from peers or mentors. Tools such as mock tests and practice papers are instrumental in gauging subject proficiency and areas needing improvement. Conducting SWOT (Strengths, Weaknesses, Opportunities, Threats) analyses can provide a structured approach to evaluate personal capabilities. Additionally, reflecting on past performance in different subjects can help aspirants recognize patterns in their learning. By prioritizing revisions for weaker areas and reinforcing strengths, candidates can optimize their study strategy, thereby enhancing overall performance.
