Writing practice is crucial for UPSC Mains success, as it enhances candidates' ability to articulate complex ideas clearly and coherently. Regular writing exercises familiarize candidates with the exam format, helping to improve time management during the actual test. Practicing structured answers and developing a distinct writing style allows candidates to express their thoughts persuasively. Furthermore, receiving feedback on written responses helps identify areas for improvement, ultimately leading to better performance in both the Mains examination and the interview stage.
