Many a times, sincere candidates fail in Government job exams because
- Relying on readymade guidebooks by “jholachhap publication”.
- They underestimate the level of competition and hence their preparation is not upto the mark. [although personally they may be believing that they’ve studied hard.]
Know that whether it is IAS exam or Bank clerk’s exam, competition is always tough and life is always cruel [thanks to our population]. Hence, The only way to make life easier, is studying harder and harder.
Readymade guidebooks for ACIO exam
As I keep saying: DONOT USE any readymade book such as “ACIO/APFC/CPF guidebook by XYZ bogus publisher. ”
Reasons:
- They merely copy paste few chapters from here and there, donot provide you comprehensive information / theory on any topic.
- Secondly, many candidates simultaneously prepare for SSC, LIC, CPF, IBPS and similar exams, so they’re really good both in GK as well as aptitude. You prepare from some ‘jholaachhap” book then you loose in the competition.
How to approach the Objective paper of ACIO exam?
I’m grateful to the good friend CSL180 for providing the inputs on previous papers of ACIO exam.
From the previous trend, it seems ACIO is more about GK than GS.
Difference between GK and GS
| General Knowledge | General Studies |
| Kaun banega crorepati kinda things. Mere knowledge of facts. “Who, Where and When” type of questions. | encompassing much more than GK, deals with important things of life- science, Constitution, History – why this and why that – so you need not only the knowledge of facts but understanding of events. |
| Who invented Telescope? | How does Telescope work? |
- In, CPF (assistant commandant) or UPSC (IAS/IPS etc.)- the questions are less related to GK and more related to GS.
- Usually the Class I and II officers’ recruitment exams have more GS than GK but for god knows why, ACIO paper almost entirely made up of GK questions only.
- For example “NABARD was setup under which five year plan?”,
- “OPEC was established in which year?”
- May be because ACIO exam isn’t conducted by UPSC and the Old professors who setup the ACIO papers, haven’t grown out of the 90s era yet.
- Anyhow, the moral of the story is, you shouldn’t prepare for ACIO exam, the same way you prepare for UPSC, CPF or APFC. This one requires similar books but different approach.
The books
![]() |
I DONOT recommend Manorama Yearbook for GK, because
Therefore instead of Manorama, I recommend another book |
Topicwise Preparation for ACIO Exam
The NCERT can be freely (and legally) downloaded using this link Click ME.
The NCERTs contain GK information scattered throughout their chapters, Besides they’ve colorful photos and text, so they’re interesting to read.
General Knowledge
| What is asked in previous papers? | Recommended Book | |
| History | Xyz temple was built by which king? Xyz war was fought by which two sides? |
|
| Geography | Nothing from Physical Geography (Theory, atmosphere etc) Only “xyz place is famous for what?” “xyz thing is located at where?” That type of GK questions from Geography- both India and World. |
|
| Science | Who invented this and that? |
|
| Polity | Only GK For example “which article of Constitution contains provision for Constitutional amendments? |
|
| Culture | Location of Temples and fairs. |
|
| Stupid Current Affairs |
(ya, UPSC stopped asking such stupid things in Civil service exam but ACIO paper setter uncle-ji hasn’t learned the lesson yet, may the almighty give them some wisdom.) |
|
| Economy | Trivial questions like when was RBI established and when was NABARD established etc. I would expect similar GK from Current affairs based Economy. |
Current affairs material already suggested above. + Manohar Pandey |
Aptitude and English
The trivial GK is limitless, but brain’s memory has limits, so how do you improve your score?
Obviously, you’ve to score huge in English Grammar and Aptitude.
There are aspirants in this “competition business” for 2-3 years, trying for Bank, LIC, CPF, SSC and similar jobs, and they’ve impeccable command over English grammar/Reading comprehension and aptitude.
So if you make any excuse ki “meraa English thik nahi hai” or “meraa maths kamjor hai”, then you’re digging your own grave. Toppers donot fall from sky, they’re among you, but they’re just studying harder and not wasting time in giving such excuses or doing cut off speculation. So, If your maths/english is not good, then study hard and improve it. Know that every master was once an amateur.
English Grammar and Vocabulary
Sentence correction, Sentence arrangement, Reading comprehension, synonym, antonym, fill in the blanks etc.etc.etc.
Study approach and booklist is same, as given in earlier APFC exam article: Click ME.
Aptitude
Since you’ve applied for ACIO exam, I assume that your end goal is Government job of some kind.
So even if you fail in ACIO, you’d continue pursuing similar competitive exams such as IBPS, SSC, LIC, CPF etc.Therefore, I would suggest the aptitude books that can be used for all such exams.
![]() ![]() |
For ACIO exam, prepare upto level 1 exercises only from each each chapter. Ideally you should do all the sums from all the chapters, Including the Non-Verbal portion i.e. figure based questions.
And most importantly, no one can master aptitude by reading the solved sums alone. You’ve calculate them by your hand. |
Sidenote:
- If you’re running out of time, you may use IBPS Manual by Disha Publication

instead of the book #1 and Book #2 given above. But that’s like firefighting and such shortcuts are luck dependent, hence should not be used in normal case.
Essay
The ACIO 2012’s notification specifically mentions that
ACIO-II/Exe contains two papers namely
Paper I (Objective type) and
Paper II (Descriptive type on English language only).
The total duration for both the Papers is 1 hour and 40 minutes.
- It means you’ll have to write Essay in English (Paper II).
So how to approach this essay?
First read this article on how to write an essay: Click ME - Second, go through this book “A book of Essays by Spectrum Publication

This book has around 100 essays on various themes and topics, so you get enough fodder material for writing essays on conventional topics.
Apart from that daily newspaper reading: Either The Hindu or Indian Express.

Go man. Its good Job. This is also all India Service.
If you want to serve for your country then you should join this.
AC jyada behtar hai iss job se so go for assistand comdnt.all the best
See chetan ,even if you get selected in CAPF(AC) -2013 you will get you joining only a year later and in the mean while you can get some real job experience which can help you in future when u would ask for deputations into other depts related to intelligence,so i suggest you to join ACIO and shift to AC later,moreover the bond amount is 60000or 3months salary which you can easily save once in the job but you cannot get any job experience like IB ACIO anywhere in any organisation in the world (remember IB of india is the oldest Intelligence organisation of the world )
Dear chetan kindly tell how to prepare for cpf-ac exam .you can mail me at lazem13@gmail.com

Hi,
I am interested in acio, because of its adventurous carreer. meanwhile, i am an civil service aspirant.
How acio works? Is that safe, especially for girls. whats the scope of girls in this career?
It is more safer because ,it is more or less a desk job for girls.My friend’s sister working as SA-security assistant(constable) working in IB chennai for last 2 years havent travelled anywhere.But for boys it will be an extensive travel.For example if a guy posted in chennai after training,he’ll be visiting his IB office twice a month and remaining 28 days he has to travel all over india for spying.They’re spying criminals,politicians,ias,ips,bigshots,illegal business people.So it is more dangerous rather than adventurous.More like Sub inspector work but without a gun.Till the end of your career u never get a gun to shoot any criminals unless u are a top ranking officer. Better choose assisstant commandant it will be extreme adventurous as well as dangerous.Be like a legend till u exit. All the best.
