General Knowledge and Reasoning
General Knowledge and Reasoning checks stable general awareness plus pattern-based thinking. GK items may cover Bangladesh and world geography, national symbols, civics, science in daily life, sports and international organisations; reasoning items use series, analogies, classification, directions, coding and simple logical deduction.
Core rules
- Use reliable static facts: Bangladesh’s capital is Dhaka; the UN was founded in 1945 and its headquarters is in New York; SAARC’s secretariat is in Kathmandu.
- In number series, compare consecutive differences, then second differences if needed.
- In analogies, state the relationship in a precise sentence before choosing.
- In direction puzzles, draw a quick compass sketch and mark turns.
- In classification, find the shared category and eliminate the odd item.
Worked example
Find the next term: 3, 6, 11, 18, ?
Differences are 3, 5, 7 - consecutive odd numbers. The next difference is 9, so the next term is 18 + 9 = 27. Checking: 3+3=6, 6+5=11, 11+7=18, 18+9=27. The rule must fit every pair, not just the first two.
Traps that cost marks
- Relying on outdated current facts; prefer stable facts you can verify.
- Missing qualifiers such as not, all, only and except.
- Forcing a familiar series rule without testing it on every pair.
- Confusing left and right after a turn in direction questions.
- Choosing an answer because it sounds important rather than because it fits the stated relation.
- Ignoring the order of items in coding or ranking puzzles.
