Best practices for staying updated on socio-political changes relevant to UPSC include subscribing to reputable news sources, following current affairs magazines, and engaging with designated apps that filter news by categories. Setting aside dedicated time each day for reading news articles ensures consistent awareness. Participating in discussions or study groups can also help reinforce knowledge and provide differing viewpoints. Additionally, taking notes on significant events or changes and reviewing them regularly sustains retention. This proactive approach creates a strong foundation of current knowledge, essential for both the prelims and mains of the exam.
