  • Intelligence Bureau (IB) had conducted written examination for requirement of Assistant central intelligence officer (ACIO) on 22nd February 2015.
  • I’m preparing the topic wise ACIO Answerkey in four parts.
  • First part: History and Polity MCQs already published
  • Second part: Economy and Geography MCQs also published
  • In this third part, we’ll look at Science and Persons in News (PIN) type questions.
  • Since IB refuses to disclose cutoffs under right to information act (RTI), so not much point in dwelling into that. One exam is over then it’s time to prepare for another exam.

Science Questions in ACIO-2015

  • Out of the 15 questions, most were tough because these topics are not part of routine preparation of NCERT and LucentGK. Some of them even trivial GK type, such as Homi Bhabha was founding director of TIFR or Who was batchmate of S.N.Bose.
  • Nobel Prize questions about Einstein and Raman are tricky in nature.
  • Nothing from current affairs related to Nobel prize, Ebola, Mars-Mission, Neutrino-Observatory etc.
  • Nothing asked from computer awareness. (in 2013, they did ask).
  • Strategy for Next ACIO exam: at minimum NCERT and LucentGK should be prepared. Main focus should be on theoretical portion.
