Improving clarity and coherence in UPSC answers can be achieved through several techniques. Employing a clear structure that uses headings and bullet points can make answers more digestible. Candidates should avoid jargon and aim for simple language to ensure comprehension. Using transitions between points aids in maintaining flow. Practicing revision and editing is crucial; well-refined answers tend to be clearer. Regular feedback from peers or mentors can provide insights on areas needing improvement, thereby enhancing overall communication effectiveness.
