## The Importance of Data Sufficiency Questions in GMAT

~ by our Maths Faculty

My opening GMAT blog post will focus on Data Sufficiency, an important and unique Quantitative Reasoning question type in GMAT. Later on we’ll take up some sample questions to illustrate how to tackle this strange and interesting question type but first we will look at a fundamental point: why is DS important? Well, look at Figure 1 below

Figure 1

What this pie chart tells us is that, out of 37 questions in the GMAT Quantitative Reasoning section, you can expect around 22 to 23 will be of the Problem Solving (PS) type and 14 to 15 of the Data Sufficiency (DS) type.

## Did You Know these Facts about GRE Math?

~ By our Quantitative Reasoning Faculty

April is almost over and the countdown to the exam has already begun. You want a good overall score and if you’re an engineer, you are most probably thinking that getting 165 on Quant shouldn’t be too much of a problem (the typical engineer approaches maths questions with a raw “Just bring ‘em on” kind of arrogance and usually gets most questions right). But here’s the problem: sometimes even those with a strong background in maths may not cross the 160 mark – and when that happens, dreams of a score in the 325+ range come crashing down. To prevent that unhappy outcome, here are some basic insights about the way the math works on GRE.

## What Happens if I Get a Low Score in the TOEFL or IELTS?

What is the Minimum Score Required?

Most American Universities regard a score of 80 (out of 120) in TOEFL, as an acceptable minimum score for admission. However, students applying to high-ranking colleges generally need a minimum score of 100 on TOEFL or, a score of band 7 (out of 9) on the IELTS. What happens if you get a lower score than you require? Does that mean that admission is not possible?

What if I have Less than the Minimum Score Required?

For students, a low score does not necessarily mean an application reject. University admissions committees assess English proficiency based on other application criteria, apart from test scores. In case your score is less than the minimum required you may need to take an English Language course in the University, followed by a test. This course will have to be taken along with the regular curriculum and you will be required to pay an additional fee for it. The best thing to do is to retake the TOEFL and improve your score before joining the University. That way you can get an exemption from the remedial English course.

## Comparison and Overview

Overall, as tests of language IELTS or TOEFL are equally easy, since both test English language skills at a very basic level. Both also contain four sections – listening, reading, speaking and writing (the essay section). Grammar is not tested in a separate section in either test; rather, it is tested as part of the other sections. But there are some differences.

The main difference between the two is the format of the test. TOEFL is internet-based (iBT), IELTS is paper-based. Further, all sections of TOEFL are tested on the same day, while the speaking portion of IELTS, which needs a scheduled appointment for a one-on-one interview, may fall on another day. There are also a few other variations in terms of testing time and in the type and number of questions asked. For example, the TOEFL, unlike the IELTS, contains integrated questions in which you may be asked to listen to a conversation, read a passage and then speak or write out a response.

## Purpose and Importance of the Tests

If you want to study abroad in countries like the US, UK, Australia and Canada, and if your first language is NOT English, you will have to take a test to prove that you can speak, read, write in English and understand spoken English. Two major standardized assessment tests allow you to do this: TOEFL (Test of English as a Foreign Language) and IELTS (International English Language Testing System).

These tests allow foreign universities to see whether students have at least the basic language skills required to complete their courses. That is why it is mandatory to take one of these tests if you are applying to graduate or undergraduate study programs abroad. In fact the TOEFL and IELTS have become the gold standard of English proficiency for educational purposes and also for immigration and work. But which of these exams should you take?

## An Easy Way to Learn GRE Test Words – Learn Them through Roots

Starting this week, we are introducing a new feature that will help all you students who are struggling to prepare for the GRE test – posts that will help you learn the GRE test words using roots. Though the technical meaning of ‘roots’ is a little different, here it is useful to think of them as the original Latin and Greek words that the English words came from.

Learning words through their roots is useful in two ways – firstly, knowing the root and meaning of a word can help you understand why the word means what it means. Secondly, since there are often many words which come from the same Greek or Latin root, this helps you to learn several words at one time. It becomes easier because, as you will seen in today’s post, words from the same root look similar and also share a common set of meanings. The two lists below, which cover 32 words totally, will illustrate how this is so.

## An Easy Way to Learn GRE Words (Through Roots) Part 2

If you found the last post on roots helpful, here are 2 more roots which cover 25 GRE words. For those of you who have come directly to this post, here’s a link that will help you understand why we are talking about roots so much: go to first roots post. (But basically, it helps to make learning the GRE words much easier).

genus generis (14 words)

The Latin word genus (cognate with Greek ‘genos’ and the Sanskrit root ‘jan’) has produced a number of English words. Genus has two basic forms: ‘genus’ and ‘generis’ (the second of which is more important because most derived words in English and other modern European languages have come from it whereas ‘genus’ exists as a single English word).
