How to Prepare Geography & Environment for Government Exams
Always locate a news event on a map. Geography questions link topical news to physical location. Practice placing events on a blank India map.
Environment news is high-yield. Track new Ramsar sites, World Heritage sites, and biosphere reserves added each year.
For UPSC, read about climate policy outcomes alongside geography. IPCC reports and India's emission targets are core material.
