To write concise and impactful essays for UPSC, candidates should first brainstorm and outline main ideas before starting to write. Structuring essays into distinct sections – introduction, body, and conclusion – allows for better clarity. It is crucial to use examples and case studies to support arguments while avoiding unnecessary jargon. Practicing previous years’ essay topics improves writing speed and coherence. Staying focused on the question and maintaining a clear argument throughout the essay will ensure a strong, impactful submission.
