Prelims Strategy

Focus on memorizing specific facts about key institutions: MAC's three-tier structure (MAC-I, MAC-II, MAC-III), NATGRID's 21 databases from 10 agencies, CCTNS connecting 15,000 police stations, and DIA's 2019 establishment.

Remember constitutional provisions (Articles 355, 246) and legal frameworks (RTI Act Section 24, NSA 1980). Practice elimination techniques by understanding agency-specific functions: IB handles domestic intelligence and MAC coordination, RAW focuses on external intelligence, NTRO provides technical intelligence, DIA coordinates military intelligence.

Common traps include confusing controlling agencies (MAC under IB, not RAW), establishment timelines (MAC in 2001, not post-2008), and functional distinctions between platforms. Use acronyms for technology platforms: NATGRID (National Intelligence Grid), CCTNS (Crime and Criminal Tracking Network & Systems), NCCC (National Cyber Coordination Centre).

Pay attention to recent developments like DIA creation, AI integration, and international agreements which frequently appear in current affairs-based questions.
