Improving writing speed for UPSC exams can be achieved through consistent practice and timed writing exercises. Candidates should set daily word count goals or complete practice papers under time constraints. Familiarity with the exam pattern and types of questions allows for strategic planning of answers. Focusing on clarity instead of complexity helps streamline thought processes during writing. Utilizing headings and bullet points can aid in organizing responses efficiently. Additionally, feedback from peers or mentors can provide insights to refine writing techniques further.
