General Knowledge and Current Affairs
Core concepts
This domain covers static general knowledge (world geography, capitals, currencies, international organisations, science basics, sports, awards) and current affairs (national and international events, appointments, summits, treaties, economic indicators). A police sub-inspector is expected to know Bangladesh's administrative setup, major national institutions, and recent developments.
Traps
Current-affairs questions are time-sensitive: an option may be correct for a past year but wrong now, so check the year in the stem. Organisations are often confused by headquarters or founding year (UN, SAARC, BIMSTEC, OIC, ASEAN). Currency and capital pairs are swapped. Science questions mix units (watt vs joule) or confuse a device with its principle. Sports questions swap host country and winner.
Rule of thumb and worked example
Build a one-page table per topic: organisation, headquarters, founding year, member count. For example, the UN was founded in 1945 with headquarters in New York; SAARC in 1985 with its secretariat in Kathmandu. When a question names a year, verify each option against that year before choosing. For appointments, note the designation and the date together.
Study method
Keep a rolling monthly current-affairs log and revise it weekly; static facts should be revised through short quizzes rather than long reading.
