Aspirants can identify their weak areas during UPSC study by conducting regular self-assessments through mock tests and previous year’s question papers. Analyzing performance in these tests reveals topics that are consistently challenging. Creating a diagnostic report can help in visualizing strengths and weaknesses, which can then guide focused revision. Additionally, engaging in discussions with peers or mentors can provide insights into areas needing improvement. Reflecting on feedback and actively revisiting tough concepts further aids in understanding and retention.
