Master Content 61 - 70
BPSC MAINS — MASTER CONTENT 61–70
I’m treating 61–70 as the high-yield GS-II/Geography/Science-Tech cluster, built around recurring BPSC question families rather than isolated textbook chapters. The PYQ corpus from 48th–70th BPSC shows particularly strong recurrence in agriculture, Bihar economy, monsoon/climate, water, environment, space, energy, health, IT/cyber and technology-development themes. (iasvalley.com)
MASTER CONTENT 61 — AGRICULTURE, FARM PRODUCTIVITY & FARM INCOME

🎯 TOP RECURRING QUESTION FAMILIES ACROSS 61–70
Based on the 48th–70th BPSC PYQ corpus, these are particularly valuable recurring families:
Agriculture → productivity → farmer income
Bihar → growth → backwardness → disparity
Migration → causes → consequences → solutions
Monsoon → agriculture → Bihar
Climate → environment → development
Water → scarcity → technology
Energy → demand → sustainability
Technology → development
Technology → environmental consequences
Digital technology → governance/security
Space → national development
Health → science/technology → human development
The broader PYQ databases corroborate that BPSC repeatedly revisits these families rather than treating them as isolated one-time topics. GS-II alone has been categorised into 182 questions across 64 themes for the 48th–70th cycles, while GS-I contains 160 questions across 88 themes. (iasvalley.com)
