Class 10 Social Science is the most UPSC-relevant NCERT after Class 12. The History book covers nationalism in Europe and India (freedom movement themes), Industrial Revolution, and Print Culture. Geography covers resource management, agriculture, minerals, manufacturing, and lifelines of economy — all critical for GS Paper 3. Civics covers federalism, power sharing, gender, political parties, and outcomes of democracy — core for GS Paper 2. Economics covers development, sectors (primary/secondary/tertiary), money and credit, globalisation, and consumer rights.
