Aspirants can assess their performance in the Preliminary Examination by analyzing their responses post-exam, using tools like answer keys and coaching institute materials. Conducting a self-evaluation helps identify strengths and weaknesses in subject areas. Taking mock tests based on the actual format of the Preliminary exam allows candidates to simulate exam conditions and measure improvement over time. Furthermore, reviewing performance across different sections assists in strategic planning for future attempts, ultimately leading to enhanced preparedness and focused study efforts for subsequent examinations.
