Aspirants can effectively utilize social media for UPSC preparation by following credible pages that share relevant content. Engaging with online study groups fosters collaboration and knowledge sharing. Using platforms like Twitter and YouTube can provide access to expert tips, resources, and current affairs updates. Aspirants should avoid distractions, focusing instead on channels that cater to UPSC-specific content. It's essential to maintain a disciplined approach to ensure the time spent on social media adds value to their preparation rather than detracts from it.
