Aspirants can objectively assess their performance throughout UPSC preparation by employing tools such as self-assessment tests and mock exams. Regular reviews of study schedules and completion rates of syllabus portions are also beneficial. Feedback from mentors or peers can offer insights into areas requiring improvement. Keeping a progress diary helps track achievements and setbacks, promoting reflective learning. Additionally, comparing performance with peers can gauge readiness, all of which contribute to an ongoing evaluation of their preparation efforts.
