BCS Written Geography case studies
BCS Written Geography · Put your knowledge to work in context.
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 case studies are 5 cases and about 2,696 words.
