Candidates can critically evaluate their own preparation using methods such as self-assessment, regular practice tests, and feedback from peers or mentors. Setting measurable goals and reviewing performance periodically helps identify strengths and weaknesses. They should analyze previous years' question patterns and align their study materials accordingly. Engaging in mock interviews and group discussions can also provide insights into communication skills and knowledge gaps. Additionally, maintaining a study journal to track progress and reflections can highlight areas requiring further focus, thus enhancing the preparation process.
