Aspirants can assess their preparation level for UPSC exams through a combination of self-evaluation and performance metrics. Regularly taking mock tests allows candidates to gauge their understanding and speed, identifying strengths and weaknesses. Comparing performance with previous results can indicate progress. Additionally, reviewing feedback from mentors, peers, or evaluation platforms aids in recognizing areas needing improvement. Maintaining a detailed study journal documenting topics covered, time spent, and difficulties faced further helps track growth. Engaging in group discussions or peer reviews can also provide external perspectives on one's preparedness.
