Is it necessary to refer to multiple sources for UPSC preparation?

Referring to multiple sources can be beneficial for UPSC preparation. It helps in gaining diverse perspectives, cross-verifying information, and understanding topics comprehensively. However, it is important to strike a balance and not get overwhelmed by too many resources. Begin with standard books and study materials recommended by experts. As you progress, selectively refer to additional sources like newspapers, magazines, research papers, and online platforms to deepen your understanding and stay updated with current affairs. Consolidate the information from various sources, make concise notes, and focus on understanding concepts rather than accumulating excessive
information. Remember that the quality of preparation matters more than the quantity of resources, so choose reliable sources and focus on thorough understanding rather than superficial coverage.
