Map-Reading Tips for UPSC
Prelims pattern: Questions appear as "Which of the following countries shares a border with X?" or "The strait connecting A and B is —" or "Identify the country/river/pass on the map."
Mains pattern (GS1/GS2): "Discuss the strategic significance of [strait/region]"; "Explain the geopolitical importance of [country/location]."
What to memorise: Straits (which seas/oceans they connect), countries bordering disputed zones, continent-wise major rivers and mountain ranges, and locations of key current-affairs countries.
