Crack CAT with self preparation
A high score in your entrance exam is a must to pursue your MBA dream but to get that to happen and how you do it is also important. While most choose to crack that entrance exam by joining coaching institutes, there are some that wish or want to challenge themselves by taking up the task themselves. However, the one question that crosses everyone’s mind before beginning with the preparation is ‘Will I get a high score in my entrance exam and will it be enough to get me through to the top B-schools?’ and it most definitely weighs more on the minds of the ones that wish to prepare themselves without coaching. We are bringing you 6 different methods or ways through which you can crack CAT without coaching. 1. Know your exam The first thing you prepare for is getting to know the exam pattern and syllabus of CAT in detail. Next, a comprehensive plan needs to be in place before you start preparing for the exam. To do this, you need to go through previous years’ question papers and analysis so you can understand the importance of each topic and set your priorities accordingly. Generically the exam is a multiple choice test with main focus on 4 major areas, viz. Quantitative Ability, Verbal Ability, Data Interpretation and Logical Reasoning. 2. Right Study Material There is ample study material available even for those who do not take coaching for CAT. A lot of books, question banks, preparatory books, and sample question papers are available in book stores as well as the online market. Getting the right material is important for systematic studies. Make use of sample question papers and practice papers to understand your strengths and work on your weaknesses. ‘How to prepare for Quantitative Aptitude for CAT’ by Arun Sharma, ‘Quantitative Aptitude Quantum CAT’ by Sarvesh Verma, and ‘The Pearson Guide to Quantitative Aptitude for the CAT’ by Nishit Sinha are some of the books, written by experts, that can be used for self-study and reference. Getting your general knowledge up-to-date is also important. You can go through various newspapers and magazines to do so. 3. Online Mock Tests Once you are done with your basic preparation it is necessary for you to take online mock tests to understand where you stand on the ladder of preparation. This analysis is very important as it helps you to change or continue on your path of action accordingly. Start with one to two tests a week initially and then move up to 3-4 tests a week. Note down your silly and common errors in each test you take so you can avoid them in the future. There are a lot of coaching institutes where you can enrol for the test series without attending the CAT classes there. 4. Study Group Anything can be achieved if you join forces. You can form a little study group where you can bounce off ideas on how to prepare for a particular topic in CAT or which is the best way to deal with a topic, etc. Discussing problems, sharing your queries and strategies helps you prepare better.

How to crack XAT Decision makling
Decision Making (DM) is a section unique to XAT and consists of a mix of behavioral, managerial and mathematical questions. Decision Making is not really a test of theoretical knowledge but challenges the basic assumptions of your thinking and whether you are able to understand real-world problems that are presented as cases in these questions. The mathematical decision-making questions can be regarded as Data Interpretation or Logical Reasoning sets that can be solved using the techniques adopted for these areas. Keep in mind that these questions are generally very data-intensive and require in-depth analysis. Make sure that you quickly scan through the problem and only solve them if they appear to be manageable within a decent amount of time. The behavioral and managerial questions in the section are the interesting ones. Generally, you are provided a situation in which multiple courses of action arise or there are multiple fallouts of a particular action, and you are supposed to identify the correct path/ analysis. Majority of the time, the questions pose ethical/ management/ human resource related dilemmas that you are expected to address and solve. Effectively, you can view these questions as a combination of critical reasoning and reading comprehension questions. In terms of how the questions appear in the exam, the following types are seen: Single Question Prompts: These mimic critical reasoning questions, where a single paragraph is followed by one question. Generally, you should go through majority of these questions as these are not time intensive and you can easily gain a foothold in the section using these. The number of such questions has increased in the last couple of years. Two to Three Question per Prompt: These questions consist of a moderate prompt followed by 2 to 3 questions. On a number of occasions, long caselets have been provided by XAT, which have been followed by only 2 or 3 questions. Make sure you select the questions you wish to attempt wisely as you do not want to end up wasting too much time for just 2 questions. Four to Five Questions per Prompt: These questions are generally long caselets that are followed by 4 to 5 questions. In these caselets, you generally have multiple viewpoints presented and at times, these are as long as reading comprehensions. Seven Things to be kept in Mind while solving Decision Making Questions: The above forms a cursory introduction for the decision making section and provides you few details with respect to what you can expect in the examination. In this section, we analyze the things you should keep in mind for this section. 1. Establish Stakeholders in a given problem Every situation that you are given generally has multiple stakeholders, people or parties for which that information is relevant. Make sure you make a mental list of all of these. 2. Analyze Problems Holistically: From the perspective of each stakeholder For the stakeholders that you have analyzed, make sure you are able to analyze the problem from the viewpoint of every stakeholder. Do not adopt viewpoints that neglect one side of the story. 3. Take the viewpoint that maximizes benefit and minimizes damage from a complete angle In decision-making questions, you are supposed to select the option that maximizes the benefit for the majority, and at times, this might mean selecting a course of action that might be completely risk-free. 4. Avoid personal opinions Also, do not favor any one side in any particular case. It is a common tendency of students to adopt an approach based on your own value system (for example: an anti-business or anti-worker's approach in a dispute between management and workers). Do not allow personal opinions to cloud your judgment. 5. Do not adopt unethical practices. Options that present shortcuts or unethical ways of solving a problem need to be instantly rejected. These are never be the answer. 6. Do not select options that pronounce unsubstantiated judgments. Many of the options that present extreme scenarios are actually nothing else but cleverly concealed opinions. Remember, these opinions appeal to emotion and can tempt you to select them. Be careful about them and make sure you do not get enticed by this trap 7. Question yourself and make sure you are not missing anything Majority of the time, you are faced with intricate scenarios where you miss one element or the other while solving a problem. Make sure you question yourself about these assumptions and ensure that you have not missed some vital piece of data. Along with the above, one critical thing that you need to do is to practice all previous year XAT decision making questions.
Mathematics of Group Discussion
What are the different types of Topics in a Group Discussion? A Group Discussion may be based on two kinds of topics: Factual: Such topics require familiarity with facts/information on static/dynamic components of the environment (such as social, political, economical, etc.). These topics can be further categorized into the following: Factual Generic - These topics require a basic level of awareness with respect to the various segments of our environment. They test you more on interpersonal skills, behavior and your ability to generate points, rather than discrete sectoral information. Examples: Cricket and India Issues of managing diversity in a country like India Honesty is the best policy Living in a joint family is better Guessing is an act of intelligence Factual Specific - These topics assess you on specific challenges in gathering and analyzing information on select areas. A thorough understanding of current affairs can ensure a high comfort level in handling such topics. Examples: WTO and its impact on the Indian Economy The Jasmine revolution and implications for the Arab world GAAR The Euro crisis: issues and challenges Coalgate Abstract: Such topics are based on your perception. The way you look at the topic decides your subsequent participation and performance. The challenge here is to put forth multiple implications of the topic and then evoke a discussion on some of them. Idea generation and ability to add a tangible angle to an otherwise abstract topic are the hallmarks of success here. Examples: Pigs can fly And the clock struck 13! Pink pyjamas over the Red Fort Red is red, blue is blue and never the two shall meet Black Handling Factual Topics: The first step towards approaching factual topics is to look at the topic from multiple perspectives. Try to get the reasons behind the topic/issue. This would help in covering more areas of the topic. It is highly recommended that one should not take a pre-mediated stand before the start of the topic, as it may restrict one to contribute new ideas to the topic and also the discussion becomes more of a debate. Factual Topics can be further classified into the following categories: Current Affairs Economic Education Environment IT Management Political Social Sports The techniques that you can adopt to manage factual topics are: Try and find the stake holders in the given issue- try and figure out those elements that have been responsible for the occurring of the problem. Also, figure out the elements that are going to lose or benefit from the issue A good way to start is asking why- Try to find the root of the topic i.e. what has caused this issue Try to explore the history of the topic- find the people/events that triggered the issue Discuss the Pros and Cons and offer your perspectives Give examples relevant to the issue Techniques to be used for idea generation for factual topics: SPHELTIR (Example: Reservation in India) Social- Inequalities in rural and urban India like Untouchability, Reservations for socially and educationally backward classes (Art. 15) Political- Caste based vote-bank politics Women Reservation Bill? Historical- Genesis of Caste System in India. Was there a timeline set by constitution? Economic- Creamy Layer Reservations in jobs and educational institutes Legal- Indian Constitution, Right to equality (Art. 14). However, ‘positive discrimination’ is allowed (Art. 15) Technological- Reservations in private sector like IT/ITES. Is Reservation in IITs/IIMs killing merit? International- Is Reservation making India less competitive in world? Similar policy of Affirmative Action in USA too Religion- Reservations for Minorities; Sachar Committee Report Handling Abstract Topics: The techniques that you can adopt to manage abstract topics are: Creativity and Lateral Thinking: Focus the Group on thinking as creatively as possible and then translating that thinking into concrete ideas and words Linking to factual issues: A creative idea is best if linked to a factual issue and preferably a matter currently in news Ability to understand and develop: Paying close attention to other people’s points so that they can be developed further Linking abstract concepts: Connecting two concepts to form a third one and creating a new area of thought is an impressive way to take forward the discussion Funnel Approach: An advancement of the above idea where the participant combines not just 2 or 3 but a whole range of diverse ideas to find common grounds between them and bring them together Techniques to be used for idea generation for abstract topics: POP-BEANS Example: BLACK People- corrupt/ dishonest people Objects- Black hole, manipulated balance sheet (commerce point) Place- Historical monuments, graveyard, South or North pole Behaviour- rude and aggressive behaviour Event- 26/11, other tragic events Actions- Honour killing, female foeticide , Negligent behaviour Nature – environmental degradation, catastrophic events, Society- Decline in values, morals
