Identifying weaknesses during the study phase involves self-assessment and feedback mechanisms. Regularly testing oneself with mock tests helps in discerning areas needing improvement. Keeping a record of errors made in these tests allows for targeted revision. Engaging in discussions with peers or mentors can provide external perspectives on areas of struggle. Additionally, maintaining a study journal can help reflect on challenging topics and note improvements over time. Establishing a consistent review routine fosters awareness and encourages proactive measures to strengthen those weak points.
