When discussing contemporary issues in UPSC essays, candidates should ensure to present a balanced and informed perspective. Start by clearly defining the issue and its relevance, then delve into multiple viewpoints, highlighting both challenges and potential solutions. It's essential to incorporate recent data, statistics, and case studies to back arguments. Candidates should aim to connect the topic to broader socio-economic implications and government policies. Concluding with a reflective summary strengthens the argument. Regularly reading newspapers and current affairs can significantly enhance one's understanding of relevant issues.
