UPSC aspirants can track their progress through various methods like maintaining a daily study log or calendar, marking subjects mastered and those needing further attention. Regular self-assessment tests reveal strengths and weaknesses, while feedback from mentors helps guide further study. Setting specific goals and milestones, such as completing a syllabus section or achieving a target score in mock tests, helps in quantifying improvement. Additionally, joining study groups allows sharing insights and receiving peer feedback that aids in accountability and motivation throughout the preparation journey.
