In the Assistant Central Intelligence Officer (ACIO) exam, you’ve to face two papers
- Paper I: 100 Multi-choice questions from General Awareness + aptitude (=Maths + reasoning)
- Paper II: English Essay worth 50 marks
Total time limit: 1 hr 40 minutes
In this article, we see the approach for Maths, reasoning and English.
The approach for General awareness (History, geography, science, current affairs etc.) is given in a separate article: click me
In ACIO 2012 Question paper, the internal breakup was:
Therefore, Maths+ Reasoning=9+12=21= approx. 1/5th of paper was about Aptitude. So cost:benefit is quite good but Practice@home=essential, otherwise following things will happen:
#1: silly mistakes in calculation
#2: formula problem
you won’t be able to recall formulas or you will plug wrong values in the formula=> either way answer will not come. (Example: area of equilateral triangle asked in ACIO-2012)
#3: time problem
- In maths, Because of problem #1 + #2= your answer will not match the given options A/B/C/D then you re-calculate the whole sum again=time wasted.
- In reasoning, you’ll take lot of time in each sitting-arrangement/blood-relation / coding-decoding type question. = time wasted
In short, if you want to crack a government / Bank / PSU exam=> aptitude practice@home is essential.
Maths / Quantitative Aptitude
Donot Fear Maths, Donot Hate Maths. If you basic concepts are clear and you practice enough at home, then most of maths/reasoning questions can be solved without effort or mistake during the exam.
Negative thinking “maths is too difficult, ye mujse nahi hoga”=> you’ll only dig your own grave while others prepare maths and get selected for the job.
For all competitive exams of India, we can classify math topics into following
|Regular topics||SSC/CDS/CAT exclusive||Misc Topics*|
|prepare for ACIO||Ignore for ACIO||prepare for ACIO|
(Usually non-SSC/CDS/CAT exam don’t bother much asking questions from this topics).
(Most govt-job exams nowadays don’t bother with these topics but they were asked in ACIO-2012 hence need to be prepared.)
- NCERT maths (free download @bottom)
- Any one Quantitate Aptitude book. Even second hand /used copy will work- you don’t need latest edition. Based on their utility for SSC-CGL exam, I classify the Quant books into 3 types:
|will work in ACIO + Useful for SSC-CGL; CDSBecause quadratic eq., trigonometry and geometry-theory (non-AVP) is covered properly.||
|will work in ACIO but Not so useful for SSC-CGL; CDSBecause quadratic eq., trigonometry and non-AVP geometry is not covered in length.||
|Useless for any exam||Readymade Junk from jholachhap publishers like “ACIO guide book; RBI assistant guidebook; National Insurance AO guidebook” etc.|
- For additional practice you may go through previous SSC question papers (but ignore trigonometry, quadratic equation and geometry except Area-volume-perimeter.)
Permutation combination probability (PCP)
In the late-90s, this used to be the hot-favorite topic for govt.exams, but nowadays rarely comes. However ACIO-2012 did contain two questions from PCP (meaning ACIO paper-setter uncleji still runs with 90s mindset) so you’ve to prepare PCP. Most of the PCP stuff can be solved without any formulas. Go through following articles
- [Aptitude] Permutation Combination made easy without Formulas
- [Aptitude] Combination: Coins possible Sums (without formula)
- [Aptitude] PnC: arrange such that two people Always sitting together?
- [Aptitude] PnC: How many Ways to arrange letters of word “RECUPERATE” (Permutation without Formulas)
- [Aptitude] PnC Arrange digits in ascending order to form numbers (asked in UPSC 2009)
- [Aptitude] PnC: Conditional Selection in Committee
- [Aptitude] PnC: Binomial Expansion. How many ways to select one or more out of given Items?
Additionally, I had also uploaded a few short-lectures about PCP on youtube you can see them on:
