<p>Quantitative Ability – 50</p>
<p>English Comprehension – 40</p>
<p>Social Concern – 60</p>
<p>Total &#8211; 200</p>
<p><strong>Time duration</strong> – 2 hours</p>
<p>Preparation –</p>
<h2>Quantitative Ability –</h2>
<p>The exam more closely resembles a Bank PO exam than an MBA exam. The questions seem very simple and solvable esp. for students preparing for CAT and other MBA exams. But it should definitely not be taken casually (did the same in 1<sup>st</sup> attempt and was sorry).</p>
<p>For Quantitative ability the best preparation is to take Bank PO papers. Check for Pratyogita darpan under Google Books, there are many previous issues.</p>
<p>Take a copy of only the quantitative section and solve it by setting time. Timing is very important factor because unlike other exams the time is very limited.</p>
<p>Make sure you clear the cut off comfortably.</p>
<p>The different topics covered are</p>
<p>Mathematical Aptitude (Speed, Time and Distance, Profit and Loss, Numbers, Ratio, Algebra, Series, Set Theory, Permutation and Combination, Quantitative comparison) –  &#8211; 25</p>
<p>Data Sufficiency – 5</p>
<p>Data Interpretation – 20</p>
<ul>
<li>There      is an initial set of problems based on computation</li>
</ul>
<p>E.g.: 18.5 x 22.5 x ? = 5161.5</p>
<p>Although seems simple practice these problems as there is not enough time to solve. Round off to the nearest number and solve them</p>
<ul>
<li>The      data interpretation set is the simplest and pattern is repetitive.      Practice well and do attempt all of them.</li>
</ul>
<p><strong>Analytical Reasoning –</strong></p>
<p>This part is a little tricky.</p>
<p>The different types of questions that appear normally are</p>
<ol>
<li>Selection      of Candidate based on data</li>
<li>Strong      / Weak Argument</li>
<li>Number      series reversal/interchanging etc</li>
<li>Coding/Decoding</li>
<li>Statement      and Conclusion</li>
<li>A      paragraph and 5 questions based on it</li>
</ol>
<p>With options</p>
<p>-         Definitely true<br />
- Probably true<br />
- Definitely false<br />
- Probably false Type questions<br />
- Data inadequate</p>
<p>7.Cause and Action</p>
<p>8.Groups and Conditionality</p>
<p>There can be a few more types that I might have missed out. Check online you can find Exam analysis by different coaching institute, which will give you an idea of the exam pattern.</p>
<p>Preparation for this can be solving papers of different MBA exams. IRMA sample papers are also available with a few coaching institutes</p>
<ul>
<li>The      decision making questions i.e the 1<sup>st</sup> one selection of      candidate is a must attempt even if it take more time, mainly because the      answers are right there you just need to have a little patience.</li>
<li>The      2,5,6 and 7 are tricky and will definitely be a little tough. Answer then      cautiously.</li>
<li> Answer 3,4,8 properly as they are simple.      Groups and conditionality and other questions based on data are similar to      normal MBA exams. So practice them from different question papers.</li>
</ul>
<h2>English Comprehension –</h2>
<p>This is a relatively simpler section. The different types of questions are</p>
<ol>
<li>Reading      Comprehension</li>
<li>Para Jumbling</li>
<li>Sentence      Correction</li>
<li>Fill      in the Blanks</li>
</ol>
<p>The reading comprehension section is normally a passage based on social concern like Agriculture, Environment, Education etc if you make a practice of reading these articles (which you should be doing for Social Concern section) then this section will be simple.</p>
<p>The rest of the questions are very simple, based on Basic English. If you attempt the sample papers released by coaching institutes it would me more than enough preparation for this section. But do attempt as many questions as possible.</p>
<p><strong>Issues of Social Concerns</strong> –</p>
<p>This is the toughest section in the paper. The questions mainly are around Agriculture, Environment, Education, Health, Awards, Organizational Heads.</p>
<p>Current Affairs, NGO’s, UN developmental programs etc</p>
<p>The best way to prepare for this section is to read newspaper esp. Hindu editorials. Keep a keen eye for social issues in newspaper. Cut out the relevant articles and save them.</p>
<p>This is a good site http://www.gktoday.in . Keep yourself updated with all the general data.</p>
<p>The different development programs by the government and the specific details must be memorized.</p>
<p>Read magazines like yojana, kuruskshetra and Frontline.</p>
<p>This site has good articles related to all topics http://www.indiatogether.org</p>
<p>(P Sainath articles are the best)</p>
<p>Read the book “Banker to the Poor” by Mohammed Yunus for some inspiration J.</p>
<p>Overall it’s an easy paper to crack. Although there is negative marking answer as many questions as possible.</p>
<p>Reading so many development sector articles can seem boring and it might not be required for the exam. But with time it will be an enjoyable and enlightening experience.</p>
<p>All the Best</p>

			<content:encoded><![CDATA[<p><strong>“There is no need to panic, guys;<br />
<a href="http://www.tcyonline.com/cat2009/cat_preparation.php">CAT 2009 </a>is no different from any past CAT as regards Quant &amp; DI.”</strong><br />
As a serious CAT-09 aspirant, do you completely agree to it?<br />
Although there is no need to panic, <a href="http://www.tcyonline.com/cat2009/cat_preparation.php"><strong>CAT 2009</strong> </a>is certainly different from the past CAT as regards the right ways to approach it. We have been assured many times through official notifications about CAT 2009 that IIMs are trying to keep the test as close to the old-paper-pencil-based pattern as possible. The freedom offered in a Linear-Computer-Based format supports their claim. However, the fact that it will be held on a computer screen is strong enough to make us re-visit our test taking strategies. The need to reduce or counter-balance the time-wastage-per-question, which seems to be a certain outcome of reading the data from computer screen, cannot be over emphasized. This, together with the fact that CAT Quant &amp; DI are getting more reasoning oriented, would prove our excessive dependence on the quick-calculation-faculties a mere illusion. This mirage, if not dealt with carefully today, will anyhow disappear in November end. Nevertheless, today’s mistakes would be tomorrow’s blunders.</p>
<p>THE LOGIC PREVAILS<br />
Past few years have proven to each serious MBA aspirant that a 99.99 Percentile in CAT is beyond quick calculations and Vedic Math. Though these skills are essential to set the mood, they hardly have helped a CAT taker who does not know how to logically approach a <strong><a title="CAT Data Analysis &amp; DI" href="http://tcyonline.com/CAT-Preparation/CAT-2010-Data-Analysis-Intepretation">Quant or DI problem</a></strong>. Probably, that’s the reason why test makers are turning towards more logical problems and less calculation-thirsty sitters. Your <strong><a title="MBA Entrance Preparation" href="http://www.tcyonline.com/india/testCategory/categoryID/100000/MBA_Entrance_Preparation_Material">MOCK Online CAT scores</a><a href="http://www.tcyonline.com/india/testCategory/categoryID/100000/free_online_mba_mock_test"> </a></strong>stand witness to the hard fact that as the Quant and DI problems turn more logical the time per question is bound to increase. This is because a logical problem needs a logical solution and to break the code you must spend time analyzing the given data. Hence, there is a need to curb this time-flu before it causes major damage.</p>
<p><strong>A HOLISTIC APPROACH</strong><br />
If we analytically assess the challenges a computer can pose, we can reach the so called Holi-grail strategy for CAT-09 Quant and DI. The analysis by <a href="http://tcyonline.com/india">TCYonline</a> experts broadly exposes 5 major challenges a CAT 09 Quant or DI problem can pose. They are:<br />
<strong>1. Concentration</strong><br />
Challenge… which is the root cause of “having to RE-RE-RE-Read” a question statement / answer choices / a chart / an equation in order to un-lock the relevant information in it.<br />
<strong>2. Optical</strong>-Illusion Challenge… which leads us to assume the “Not-otherwise-givens” thereby deviating from the logic and falling into the set trap.<br />
<strong>3. Challenge of Relevance</strong>… which, if ignored, may push us into the data-ware-house-of-the-chart or graph.<br />
<strong>4. Challenge of Consistency</strong>… which although a by-product of poor concentration on computer screen, can challenge our capability to stay consistent with a single unit of the data – especially the one used in the answer choices.<br />
<strong>5. Challenge of Interpretation</strong>… which is caused by many statements which are difficult to retain in mind (because you cannot highlight any of them).</p>
<p>And there is only one way to meet these challenges – “Common-sense”. However, it can be easily translated into specifics as follows <strong>challlenges:</strong><br />
<strong>•	Concentration</strong>•	Optical-Illusion<br />
<strong>•	Relevance<strong>&gt;•	Consistency Interpretation</strong><br />
This has been explained in an example from past CATs below<br />
Here are a few examples from the Past CATs:</strong></p>
<p><strong><strong>Concentration</strong><br />
<strong>Question 1:</strong> In a tournament, there are n teams T1, T2, &#8230;,Tn, with n &gt; 5. Each team consists of k players, k&gt;3. The following pairs of teams have one player in common:<br />
T1 &amp; T2, T2 &amp; T3, ……., Tn – 1 &amp; Tn and Tn &amp; T1<br />
No other pair of teams has any player in common. How many players are participating in the tournament, considering all the n teams together?<br />
(1) n(k – 1)<br />
(2) k(n – 1)<br />
(3) n(k – 2)<br />
(4) k(n – 2)<br />
(5) (n – 1)(k – 1) <a href="http://www.tcyonline.com/india/testCategory/categoryID/100000/free_online_mba_mock_test">(CAT 2007)</a><br />
<strong>Solution 1 : </strong><br />
Such question statements demand good concentration. Here, the given pairs confuse us. However, if we start formulating the problem on the scratch paper as we read, life gets easier.<br />
For instance, Our notes go something like this:<br />
 There are “n” teams<br />
 “k” players in each team<br />
 “n” pairs (the confusing part was this simple) of teams have 1 player in common.<br />
So, the answer is nk – n = n (k– 1).<br />
<strong>Answer (1)</strong></strong></p>
<p><strong><strong>Optical-Illusion</strong><br />
Question 2 : In the figure, AB = BC = CD = DE = EF = FG = GA. Then DAE is approximately<br />
<a href="http://www.tcyonline.com/blog/wp-content/uploads/2009/09/triangle1.jpg"><img class="alignleft size-full wp-image-241" title="triangle1" src="http://www.tcyonline.com/blog/wp-content/uploads/2009/09/triangle1.jpg" alt="triangle1" width="300" height="225" /></a><br />
1) 15o<br />
(2) 20o<br />
(3) 30o<br />
(4) 25o<br />
<strong>( CAT 2000)</strong><br />
<strong>Solution 2:</strong> It is given that AB = BC = CD = DE = EF = FG = GA; However, in the figure, these sides do not seem to be equal. Hence, in order to accurately reach the solution, we have to proceed with the given data and NOT according to the given figure.</strong></p>
<p><strong>Work from the choices.<br />
If we put A = 15, then C = 15 (isosceles) and then keep calculating the angles further we can reach the solution fast (for this you must have drawn the figure on to the scratch paper).<br />
Make adjustments in your assumptions by keeping in mind that the sum of angles of the big triangle must be 180o<br />
You will find that only 25o comes as the result.<br />
<strong>Answer (4)</strong></strong></p>
<p><strong>Relevance<br />
<strong>Question 3 :<br />
<a href="http://www.tcyonline.com/blog/wp-content/uploads/2009/09/bar3.jpg"><img class="alignleft size-full wp-image-243" title="bar3" src="http://www.tcyonline.com/blog/wp-content/uploads/2009/09/bar3.jpg" alt="bar3" width="300" height="225" /></a><br />
</strong>(Note: Availability is defined as production less export.)<br />
<a href="http://www.tcyonline.com/blog/wp-content/uploads/2009/09/bar22.jpg"><img class="alignleft size-full wp-image-244" title="bar22" src="http://www.tcyonline.com/blog/wp-content/uploads/2009/09/bar22.jpg" alt="bar22" width="300" height="225" /></a><br />
In which year during the period 1996–99 was Chaidesh’s export of tea, as a proportion of tea produced, the highest?<br />
(1) 1996<br />
(2) 1997<br />
(3) 1998<br />
(4) 1999<br />
<strong>(CAT 2003)</strong><br />
<strong>Solution 3 :</strong> A lot of data, isn’t it?<br />
But if you really refer to the question first you will find that in order to answer it, we don’t at all require the first chart. Just concentrate on the required data to solve this question.<br />
From second chart we can say that it is highest in 1997.<br />
Hence, remember – the more you read without referring to the question, the more you’ll get confused (and therefore waste time).</strong></p>
<p><strong><strong>Consistency :</strong>Directions : Eighty five children went to an amusement park where they could ride on the merry-go-round, roller coaster, and Ferris wheel. It was known that 20 of them took all three rides, and 55 of them took at least two of the three rides. Each ride cost Re 1, and the total receipt of the amusement park was Rs 145.<br />
<strong>Question 4 :</strong> How many children did not try any of the rides?<br />
(1) 5<br />
(2) 10<br />
(3) 15<br />
(4) 20<br />
<strong>Question 5 :</strong> How many children took exactly one ride? .<br />
(1) 5<br />
(2) 10<br />
(3) 15<br />
(4) 20<br />
<strong>Solution 4 &amp; 5: </strong><br />
Total children = 85<br />
Children who have taken 3 rides = 20<br />
Children who have taken 2 rides = 55 – 20 = 35<br />
Children who have taken 1 ride = 145 – (20 × 3 + 35 × 2 ) = 15<br />
Children who have taken 0 rides = 85 – ( 20 + 35 + 15) = 15.</strong></p>
<p><strong>Therefore, if we put all the given information in a consistent way, we can answer both the questions together.</strong></p>
<p><strong><strong>Interpretation : </strong><br />
Question 6 : A chemical plant has four tanks (A, B, C and D), each containing 1000 liters of a chemical. The chemical is being pumped from one tank to another as follows:<br />
From A to B @ 20 liters/ minute<br />
From C to A @ 90 liters/ minute<br />
From A to D @ 10 liters/ minute<br />
From C to D @ 50 liters/ minute<br />
From B to C @ 100 liters/ minute<br />
From D to B @ 110 liters/ minute</strong></p>
<p><strong><strong>Which tank gets emptied first and how does it take (in minutes) to get emptied after pumping starts?</strong><br />
(1) A, 16.66 (2) C, 20 (3) D, 20 (4) D, 25 (CAT 2005)<br />
<strong>Solution 6 :</strong> Would you take the chance to write all the data on the paper again???<br />
Hey! You have got to work smart here!<br />
Just put the given information in the required format.<br />
&#8211;A &#8212;&#8212;&#8212;&#8211; B&#8212;&#8212;&#8212;&#8212;&#8212;-C&#8212;&#8212;&#8212;-D<br />
- 20 &#8212;&#8212;- + 20&#8212;&#8212;&#8212;&#8211;+ 90 &#8212;&#8212;- &#8211; 90<br />
- 10&#8212;&#8212;&#8212;+ 10 &#8212;&#8212;&#8212;- &#8211; 50&#8212;&#8212;- + 50<br />
- 100&#8212;&#8212;&#8211;+ 100&#8212;&#8212;&#8211; + 110&#8212;&#8212; &#8211; 110<br />
50 liters is going away from tank D every minute. Hence it will get emptied first and in 1000/ 50 = 20 minutes.<br />
Answer (3)</strong></p>
<p><strong>A few more things one can exercise in his MOCKs are:<br />
• Keep in mind the same old plan of doing the paper in 3 rounds. Now as the test is on computer you must follow a very logical approach to select the questions in Round 1 and 2. For instance, In DI you must attempt the questions that can be answered by read minimum information from the graphs / charts. In Quant, ones involving minimum equations should be preferred. Also, sometimes there are 2 – 3 questions based on one set of data. They are also expected to consume less time once the problem is properly drawn on to the scratch paper. Here we are assuming that Prometric will allow you to move back and forth among the questions. However, if it did not allow (highly unlikely) you to move back, your time per question will definitely increase as you will have to skip a question only if you know you cannot do it at all given the fact that you will never come back to it.<br />
• Also it is expected that as the test goes online the percentage of Data-Sufficiency question will increase. Moreover, it is also expected that the amount of data in the Graphs and charts will be less and with a logical approaches described above you would be able to come up winners!</strong></p>
<p><strong>All the Best!!!</strong></p>
