Aspirants can gauge their preparedness before the UPSC exam day through various methods. One effective strategy is to participate in mock exams under timed conditions, simulating the actual examination environment. This not only assesses knowledge but also identifies strengths and weaknesses in time management. Reviewing previous years' question papers provides insight into question patterns and topic weight. Self-assessments through written answers can also highlight areas needing improvement. Feedback from peers or mentors on practice answers is invaluable for refining response quality and ensuring readiness for the exam.
