Candidates should approach the revision of current affairs for the UPSC exam with a structured strategy. Regularly updating knowledge through credible sources such as newspapers, magazines, and online portals is essential. It's important to categorize information into themes such as politics, economics, and environment for better retention. Making concise notes or summaries can aid in quicker revision. Candidates should also integrate current affairs into their answers across subjects to showcase relevance in their studies. Finally, discussions with peers or mentors can deepen understanding and provide different perspectives on current events.
