MBA Abroad –II - Strategy for preparation and Study Material

Strategy for Preparation
Group with like-minded people

I advise all the aspirants to prepare in a group. Form a group of 3-4 but not more than 5 people and then start preparation. Don’t commit the mistake of all booking the GMAT on the same day, group members book your GMAT dates over a period of one month with ideally a gap of one week each, I am telling this, because one can benefit from the mistakes of others. The Advantages of group preparation are plenty: -• Books and Material required for preparation are costly, group preparation helps in sharing the costs and it gets reduced to a significant extent. • Individual people are good in individual areas and thus it helps in learning from one another. • Group mates will be greatly helpful in analyzing schools, and completing your applications, you can distribute the load and discuss the schools. • Group preparation prevents your morale from going down during preparation days. Believe me, it would be very frustrating when you appear for mock tests especially of Kaplan, so it gives you a lot of comfort when you know other people preparing are also sailing in the same boat, the discussion on mistakes will also be helpful.


Study Material

Books to Refer: -• Official Guide (OG) to GMAT, the book is available from GMAC, but its costly, I advise purchase one and share the cost or get it Xeroxed, this is the bible to crack GMAT. • Kaplan Test preparation Guide. • Kaplan 800 GMAT guide. • Princeton Review GMAT preparation guide. For GMAT preparation these four books are more than enough, I advise to start with Kaplan Test preparation and OG simultaneously. Then go through Princeton Review and finally 800 GMAT. Finally in the last 10- 15 days just revise the material, and go back on mistakes previously made, especially in the OG. For those who are poor in English, in the initial attempt its rare that one gets more then 60% correct. Revise the material and your accuracy will increase. Do OG 2-3 times and increase your accuracy to around 85- 90 %.Where to Purchase books?These books are pretty costly; each will be more than Rs1000. Search the Internet, one can get cheaper copies of originals at net, I had purchased mine from Fabmall and ebay. The copies at Internet are up to 40-50%, less, so a handsome amount can be saved. Software Required: -Kaplan Guide is available in two versions with and without Test preparation Software’s. I suggest purchasing one without Test preparation software for those who live in metros and one with test preparation software for those in non-metros. This is because; pirated copies of Kaplan Test preparation software are easily available at very low cost of Rs 80-100 in metros. GMAC also sends official preparation software to all the people who register for GMAT. Internet Internet is a big source of help; there are plenty of study forums and groups. I was late in searching these but one must join daily digests of these. I am listing some prominent ones: -www.scoretop. com www.edulix.comwww.xoxohth. comYahoo groups like Step2006intakeI recommend searching for more groups for the class you are preparing for. Every year students create these groups. People say paid version of score top is good, I had not used that one but I used its discussion forum, which I joined 5 days before my exam. I advise all aspirants to utilize maximum benefits of the score top discussion forum; also some of my friends have told me that edulix also has excellent discussion forums. I would also advise all future aspirants to read Samba’s postings at http://simba. pagalguy. com/Simba aka Sowyna is an Indian Girl. She constantly writes about her life. She is currently studying at Duke University’s Fuqua School of Business. In her posts one can find lot of insight about B- Schools and their admission process. In fact only after Inspired by her I am writing this series of articles.

Free Tests

There are plenty of free tests available in Internet. Kaplan, Princeton has a sample free test on their web site, similarly other websites also have few free tests available.


Tip’s to Score High in English

English is the most difficult portion for most of the Indian graduates, if one doesn’t agree then I am sorry but at least it was difficult for me :-) Indian Graduates are poor in comprehension. Generally the GMAT consists of 4 – 5 passages, which are quite tedious and boring. The passages are generally on American history, social differences or some new scientific discoveries. The words used are difficult and unfamiliar ones. How to crack? I suggest one should read few novels on American history. I improved my comprehension to a great extent after this. I had read Roots by Alex Haley. The novel is very boring initially but is one of the best on American history and covers a lot about life of slaves, and blacks in America, a favorite topic of GMAT exam setters. The author traces the journey of his 6 generations from African forests to current America. The other novel I had read was To Kill a Mocking Bird by Harper Lee. Also I suggest all aspirants to read Harvard Business Review, and Economist.One can improve his comprehension to a limit, but with practice one can achieve 95- 100% accuracy in Sentence Correction and Critical Reasoning. So I suggest preparing for them with full rigor.

Tip’s to Score Full in Math’s

For Indian applicants who have prepared for CAT, math’s section in GMAT is a cakewalk. For those who haven’t prepared for CAT just strengthen your fundamentals of class Xth Math and prepare for Data Sufficiency section. DS section is somewhat tough. Hope these articles are helpful to you all, in the next article I will write about selecting B-schools.

Interview Tips

As results are pouring in , congratulation to all who have cleared the first hurddle , Now comes the second one for which i have found a very good article in rediff which i am sharing with you.

Though there is no dearth of articles on interview etiquette, there is an actual shortage of good articles on the most crucial factor in an interview -- the interviewer's questions and your answers. Many problems candidates have include nervousness and stammering in an interview, which is directly related to the candidate's unfamiliarity with the questions and a general lack of preparation.
We have discussed below a few of the most commonly asked interview questions at B-school interviews. We have not given any ready-made answers to the questions, but have tried to help you arrive at the correct answer yourself, so that you sound natural and coherent in an interview.
Q. Tell me some thing about yourself.This is how most interviews begin and this is one question you cannot afford to be unprepared for.
To frame a good answer it is always helpful to know what is it that the interviewer wants to know about you. An interviewer would like to know.
~ Your educational background~ Your work experience, if any~ Your strengths and achievements~ About your family background~ About where you are coming from academically, professionally
You should be short and crisp about all the points mentioned above. If the interviewer needs an elaboration s/he will ask you.

Q. Why do you want to join this institute?This is one question you should answer honestly and pragmatically. Ideally you should choose an institute based on certain criteria. Such as
~ Ranking/ placements~ Courses offered~ Fee~ Location
It is good to do a little research on the institute, its placements and about certain specialisation(s) it may be known for. An informed analysis of the institute can convince the interviewer that you are sincerely interested. It also helps you in identifying parameters critical for you while choosing the particular institute.
Q. Which other institutes have you applied to?This is a question that is very much linked to the previous question. For example, if you say that you had chosen IRMA because you have a flair for Rural Marketing and while answering this question you don't mention the name of other institutes known to offer quality course in Rural Marketing you are in trouble. So these two questions are to be prepared simultaneously avoiding conflicts in answers.
Q. How will you add value to this institute if you make it through?This is an opportunity to showcase your strengths but remember it is essential that your strengths should be supported by related achievements.
Your background and circumstances can also be your strengths and can be used as equally important points in supporting your answer.
Remember, an achievement doesn't necessarily mean a prize. It can also be your successfully coming out of a crisis situation or you managing to run a small project with your friends.
Q. What do you consider your biggest failure?CAUTION: This is not an opportunity to pour out your darkest secrets. This is a question that is best played down. For example, if you are overweight, you may mention -- "I have been trying to shed weight for the last few years but couldn't do it still." The answer should be framed so that it does not reflect badly on your career thus far, or your future career.
Another way of answering would be a smart statement: "I have never allowed failure to drag me down. I just got up, took my lesson and picked my way forward." Here it would help to have a certain experience picked out.
Q. Why have you chosen this career?This is an area where a mature and realistic answer is expected. People choose their career based on several reasons, such as:
~ What is your aptitude?~ What kind of a social, professional and personal environment do you desire?~ What is your background and achievements?~ What motivates you? ~ What activities do you enjoy?
Q. What is the last book you read? Many experts would tell you that you should know the ins and out of the books and everything about the author and his writing style. If you know these facts, it can't hurt, but if you are not the kind of a person who would research the background and other facts about books, but read for fun, it is okay to mention it. The only thing is that your answer should be natural, convincing and rational.

For example, if the interviewer asks you for more detail about the author you may just reply.
"I'm sorry but I haven't read much about the author. But I liked this book because..."
Q. How will your contribute to this campus if we select you?This is a question that directly relates to your strengths and aspiration. Take this as an opportunity to showcase the various qualities that you possess which may benefit the college, academically, culturally or in any other way.
Q. Where do you see yourself 10 years from now?This is not when you start throwing in fancy designations. Instead, concentrate on the kind of roles people in those designations are expected to play. If the question specifically asks for your professional goals then stick to it, otherwise it is a good idea to balance it with your personal goals.
Q. Who is your role model?Your role model can be anyone � a public figure or even someone from your family. It is a good idea to know a lot about the person you would make your role model. It is important to focus on the qualities that inspire you and how you try to inculcate those qualities in yourself. It is always important to tell why s/he is different from her/his peers.
Q. Do your have any questions for me?"No" would be a bad answer. It is good to have a few questions that relate to the academic and cultural environment of the institution. This will show your enthusiasm. In a nutshell, an interview just analyses how balanced and rational you are. So, just be yourself! Preparing yourself for the questions listed above will give you the confidence to handle even unexpected questions. You should ideally write down your answer to these questions (but please don't try to mug up answers you think would be 'ideal') and practice giving interviews along these lines with a friend.
