BCS General Knowledge & International Affairs 2025: 35 Marks in Your Pocket with This Focused Guide

GK + International Affairs = 35 marks in BCS Prelim. Master both with this topic-by-topic breakdown and quick-reference system.

🌎

General Knowledge (15 marks) and International Affairs (20 marks) together give you 35 marks in BCS Preliminary — more than either English or Bangladesh Affairs individually. Yet most candidates prepare these subjects last and least. This guide reverses that mistake with a systematic, focused approach that delivers results in 3 weeks of dedicated study.

🌎 General Knowledge — 5 Core Categories

Science
4–5 questions from everyday science. Newton's laws, photosynthesis, human blood types, DNA, sound and light speed, electrical units. BCS science GK is SSC level — never advanced. Focus on the most commonly asked facts, not complex theory.
Sports
2–3 questions — always current plus historical. FIFA World Cup and Cricket World Cup hosts and winners, Bangladesh's major cricket achievements, Olympic Games host cities, Davis Cup, Wimbledon. Know Bangladesh's own sports records and achievements.
Awards
2–3 questions — Nobel Prize is always tested. Recent Nobel laureates in Peace, Economics, Literature. Ekushey Padak and Independence Award winners. Pulitzer Prize basics. Bangladesh-related international awards and recognitions.
Economy Basics
2–3 questions — macroeconomic fundamentals. GDP definition, inflation, foreign exchange reserves, WTO rules, IMF/World Bank functions, G7 vs G20 membership, World Economic Forum (Davos). Know Bangladesh's economic rankings.
Current Affairs
3–4 questions — last 12 months. Major elections, state visits, bilateral agreements, natural disasters, international summits. Read one quality newspaper daily. Keep a 1-page weekly current affairs summary and review it every Sunday.
💡
The Current Affairs System: Buy a small notebook. Every day write 5 current affairs facts in 1–2 sentences each. Review the full notebook every Sunday. In 3 weeks you will have 105 current facts memorised — more than enough to answer every current affairs question in the BCS prelim.
