BCS Written Geography study guide
BCS Written Geography · Work through your exam, one topic at a time.
Geography is one of the optional subjects available in the written stage of the Bangladesh Civil Service (BCS) examination, the competitive recruitment process for cadre posts under the Bangladesh Public Service Commission (BPSC). Candidates who select it sit a descriptive, essay-type paper rather than a multiple-choice test: answers are written in continuous prose, often with diagrams, sketch maps and labelled tables, and are marked for structure, factual precision and reasoned argument as much as for coverage. The BCS Written Geography study guide has 7 sections and about 2,330 words.
01Physical Geography: Landforms, Climate, Oceans and Life
Physical geography for the BCS written paper rewards precise causal chains rather than labels. In geomorphology , know the distinction between weathering (in situ breakdown), erosion (removal), transportation and deposition; plate boundaries (divergent, convergent, transform) and their landform signatures; the Davisian cycle of erosion versus Penck's slope-replacement model; fluvial landforms (meander, oxbow, alluvial fan, delta, peneplain); glacial (cirque, arête, moraine, drumlin); aeolian (barchan, yardang, loess); and coastal (spit, tombolo, sea stack).

Human geography examines the relationship between population, culture, settlement and space. Begin with population data : census, vital registration, and sample surveys; then measures such as crude birth and death rates, total fertility rate, infant mortality, life expectancy, and dependency ratio.
298 words, about 1 min03Economic and Resource Geography
Economic geography explains why production locates where it does and how resources shape development. Know sectoral classification (primary, secondary, tertiary, quaternary, quinary) and the shift in employment structure with development.

291 words, about 1 min07Remote Sensing and GIS
