Effective social media practices for UPSC candidates include curating informative feeds, engaging with academic content, and participating in discussion groups. By following reputable sources like UPSC coaching institutes, educators, and current affairs analysts, candidates can stay updated with relevant information. Engaging in platforms that facilitate peer interactions also enriches the learning experience and motivation. However, it is crucial to maintain a balance, ensuring that social media consumption doesn't lead to time wastage. Establishing clear boundaries around usage can help candidates remain focused and purposeful in their preparation.
