Introduction
World geography is one of the most reliable scoring areas in Bangladeshi competitive exams (BCS Preliminary, Bank recruitment, and IT-officer posts). Questions are largely fact-based and stable — a capital or a continent does not change every year — so a student who memorizes systematically and understands the underlying framework can answer almost every question correctly. This lesson builds that framework from first principles: how the Earth is divided into continents, oceans and countries; how "capital" is defined and why some countries have more than one; and a curated, exam-focused set of countries, capitals, currencies and record facts that examiners repeatedly test.
Why it matters: in a typical BCS Preliminary paper, 8–15 marks in the "International Affairs / General Knowledge" segment come directly from world geography and capitals. These are marks you can lock in with pure preparation — no reasoning risk, no negative-marking traps if you have memorized accurately.
Learning objectives
- Explain the basic structure of the Earth: continents, oceans, hemispheres, and the major imaginary lines.
- Define what a "capital city" is and distinguish administrative, legislative, judicial and commercial capitals.
- Recall the capitals, currencies and continents of exam-important countries with high accuracy.
- Identify record facts: largest/smallest country, most populous country, newest country, landlocked countries, etc.
- Solve time-zone and coordinate problems using longitude.
- Avoid the classic "trap" answers examiners plant (e.g., Sydney vs Canberra, Istanbul vs Ankara).
