Geography

BPSC’s geography questions lean on Bihar: the Ganga and its north-bank tributaries (Kosi, Gandak, Bagmati, Mahananda) and south-bank rivers (Son, Punpun, Falgu), the flood belt of north Bihar, the three agro-climatic zones, soils, minerals, rainfall and population. Indian and world geography appear at NCERT depth.

Start with Bihar geography: rivers, floods and agro-climatic zones, then Jal-Jeevan-Hariyali, the state’s water and green cover mission, which BPSC has asked about since its launch. The Bihar polity and geography PYQ set has the previous year questions on the physical geography of the state, and the Bihar economy PYQ covers agriculture, minerals and population.

Map work pays here: a blank outline of Bihar with the rivers, the districts they flow through and the agro-climatic zones is worth an hour a week. The syllabus wording is on the BPSC syllabus page.
