Practicing answer writing consistently during UPSC preparation is crucial for several reasons. It helps candidates refine their writing skills, ensuring clarity and coherence in responses under exam pressure. Regular practice allows for familiarity with the syllabus and enhances time management capabilities, which are vital during the examination. It also aids in identifying knowledge gaps and encourages a deeper understanding of topics. Furthermore, developing a structured approach to answers ensures that candidates can articulate their thoughts effectively and meet the expectations outlined by examiners.
