Techniques to improve writing speed for the UPSC Mains exam include practicing under timed conditions, developing a clear structure for responses, and employing effective time management strategies. Regular timed essay writing sessions can condition candidates to organize their thoughts quickly. Familiarity with commonly asked questions enhances preparedness. Using shortcuts in note-taking and outlining can save precious time during the exam. Additionally, practicing with previous years' papers allows candidates to gauge the time required for different sections, leading to more efficient writing during the actual examination.
