IB ACIO Grade II study guide
IB ACIO Grade II · Work through your exam, one topic at a time.
The IB ACIO Grade II recruitment exam is the entry route into the Intelligence Bureau as an Assistant Central Intelligence Officer, a Group C post that blends desk research, report writing and field coordination. It suits graduates who are comfortable moving between quantitative puzzles, reasoned argument and careful English composition, and who accept that the role carries a background check and a security clearance process beyond the written test. The IB ACIO Grade II study guide has 6 sections and about 1,581 words.
01General Awareness
General Awareness in IB ACIO Grade II is a Tier-I objective section that samples static general knowledge: Indian polity and Constitution, modern Indian history, geography, economy, general science, awards and sports. The paper rewards exact one-line facts-article numbers, years, names and institutions-so build recall around precise distinctions rather than broad reading.
262 words, about 1 min02Quantitative Aptitude
Quantitative Aptitude tests numerical reasoning through arithmetic, algebra, geometry, mensuration, trigonometry and data interpretation. IB ACIO questions are usually short but trap-heavy; the mark comes from setting up the equation correctly, not from long calculation.
276 words, about 1 min03Logical/Analytical Ability and Reasoning
Logical/Analytical Ability and Reasoning checks pattern detection and constraint-based deduction: series, coding-decoding, blood relations, syllogism, seating, puzzles and non-verbal reasoning. The section is scored on method; random guessing rarely works beyond the easiest series.
243 words, about 1 min04English Language
English Language tests standard written English: grammar, vocabulary, idioms, sentence correction, cloze and reading comprehension. The emphasis is on precision-one wrong preposition or verb form changes the answer-so practise rule-based elimination rather than ear-based guessing.
240 words, about 1 min05General Studies / Current Affairs and National Security Awareness
General Studies, Current Affairs and National Security Awareness is the section most specific to IB ACIO. It combines Indian governance, recent events and the internal-security architecture: intelligence agencies, central armed police forces, counter-terror laws, border management and cyber security.
262 words, about 1 min06Descriptive English (Essay and Précis Writing)
Descriptive English is the Tier-II writing test: an essay and a précis. It assesses structure, relevance, grammar and the ability to compress a passage without losing its argument.
