Aspirants can effectively use maps in their UPSC preparation by integrating them into their study sessions for geography and history topics. Utilizing physical or digital maps enhances spatial awareness and understanding of geographical contexts. Regular map practice can help candidates locate key places relevant to civil services. Integrating map exercises into revision sessions and making thematic maps for different subjects can also reinforce learning. Candidates should practice interpreting maps related to current affairs, as such skills frequently appear in both prelims and mains examinations.
