  • 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.

  • 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.

    Guys/girls Share your marks please…

      1. Nothing special Bhai, Already mrunal sir told it..Stepwise follow mrunal sir strategy makes you able..

      1. Excatly i don’t know about cutoff yaar..IB never revealed it..(Aakhir kuch khufiya bhi to rhne do) last year i calculated my marks was 63 in general ..and i was not in.

          1. 63 in MCQ only accordingly mrunal key, and In essay my performance was just ok type, not sufficient facts..

        1. @pravez, may I know lastyear from which place you had given this exam, as last year i qualified with this marks in gen. cat. and my interview was on 13th jan 2014.

          1. How can this possible, are you sure about your 63 marks..i appeared in varanasi region..and paper was i think only one set in all over india..And finally how was your interview? you got selection in final merit list?

          1. Hi Raghav,
            last year i wrote essay about ‘A communal conflict scenario’..And i did’t prepared any essay topic last year. So, just wrote some random datas..

          2. Might be they were preparing the merit list by adding marks obtained in both the papers(I & II).
            not just only by paper I and later adding paper II.
            (based on the sourabh’s marks last year. bcoz both of u guys got same marks)

        2. @Parvez,IB never discloses any individual marks I calculated on the basis by the answers given on MRUNAL’S web page.

          No I didn’t got selected in interview (although it went horrible),but the main cause would be my ‘meagre’ final merit score i.e(written+interview).

          IB send SMS to the selected candidates moreover results are displayed on MHA website.

          With 72 marks in gen cat. it is good (hope you had equally performed in essay), last years scenario was different.

  2. I am getting exactly 58 in objective excluding essay, let me know by your idea cut off of general including essay and excluding it too please

      1. Hi ravi .
        Do u know anyone who qualified with marks around 60 and belongs to SC category in the IB ACIO-II exam conducted in SEP 2013?

            IS ur bro from Andhrapradesh?
            Wil they add both the papers marks to make the merit list …
            wil they first check with paper 1 and later proceed to paper II?

  3. i think for r that is ideal gas ..answer should b all the gases coz…r is universal gas constant…even real gases gave consantant r …

    1. Yes it should be applicable for all gases (option 4)
      as PV=nRT( for ideal gases)
      (P+a/v^2) (V-b)=RT ( for real gases)

  4. Q9: plz correct, and should be..all gases..that’s why it is universal gas constant. For real gases also…R remains the same…only rest of the equation changes.

  5. I am getting 60 and belong to obc..what would be cut off this year? Paper was little bit tufer than previous year..is it?

  6. Hi Mrunal Sir , I am scoring 45 according to your answer key and I belongs to SC category . Is there any chance for me to qualify with this score.??

  7. Is there any negative marking? Somebody from invigilator group told us that there will be no negative marking..

    Friends, please chip in with your views.

  10. Answer for 67th is Honorary Oscar as Bharat Ratna was awarded to Satyajit Ray just before his death..pls check wikipedia


      Well, it’s an extraordinary experience for me to be here tonight to receive this magnificent award; certainly the best achievement of my movie-making career. When I was a small, small school boy, I was terribly interested in the cinema. Became a film fan, wrote to Deanna Durbin. Got a reply, was delighted. Wrote to Ginger Rogers, didn’t get a reply. Then of course, I got interested in the cinema as an art form, and I wrote a twelve-page letter to Billy Wilder after seeing “Double Indemnity.” He didn’t reply either. Well, there you are. I have learned everything I’ve learned about the craft of cinema from the making of American films. I’ve been watching American films very carefully over the years and I loved them for what they entertain, and then later loved them for what they taught. So, I express my gratitude to the American cinema, to the motion picture association who have given me this award and who have made me feel so proud. Thank you very, very much.
