Candidates can enhance their writing speed in UPSC exams by employing several effective strategies. Regular practice through timed writing exercises helps improve speed and fluency. Keeping a clear structure in mind for answers, such as defining key points in the introduction, developing them in the body, and concluding coherently, helps maintain focus. Utilizing shorthand or outlining techniques can aid in organizing thoughts quickly. Additionally, familiarizing oneself with previous year question papers can streamline preparation and enhance comfort with the exam format, leading to better time management during the actual examination.
