Quantitative Comparison Questions: Doubtful D!

~ by our Maths Faculty

Now, here’s a tip about the weird GRE question type called Quantitative Comparison or simply QC. As we know, in QC questions there are two columns, ‘A’ and ‘B’, containing some quantities. Our job is to evaluate the quantities and compare their magnitudes. In QC questions, the options are always as follows:

(A) Quantity under Column A is GREATER THAN quantity under Column B

(B) Quantity under Column A is LESS THAN quantity under Column B

(C) Quantity under Column A is EQUAL TO quantity under Column B

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.

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.

Question: How many positive integers, less than 20, are either an even multiple of 2 or, a multiple of 9 or, the sum of a positive multiple of 2 and a positive multiple of 9?

Answer: There are 11 such integers:

• Multiples of 2 – 4, 8, 12, 16 (total 4)
• Multiples of 9 – 9, 18 (total 2)
• Sums of a positive multiple of 2 and a positive multiple of 9 – 11, 13, 15, 17, 19 (total 5)

Question:

X < (1/X)

Column A Column B

X X2

The given inequality is X< (1/X).

This is possible only in two cases:

(1) If 0 < X < 1 OR

(2) X < -2

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).

Prepare to be Sentenced!

One of the most important building-blocks of an essay is the sentence. Writing an essay for an Analytical Writing Task in the GRE or the GMAT – or even the TOEFL Independent Writing Task – means that you will be expressing your thoughts in an academic context. So, you need to use sentences that are acceptable in that kind of context, but also effectively to translate your ideas onto the screen

• Complex sentences show that you are able to use the language fluently
• Clear well-formed sentences make your essay easy to understand
• Variety in sentence construction will make your essay interesting

Vocabulary Learning and Revision (to be started preferably 3-5 months in advance)

The largest, most time-consuming component of your GRE preparation is vocabulary revision. Achieving a good level of basic preparation involves getting familiar with around 4,000 words commonly used on GRE test. To really understand a word you need to know its range of meanings, some of its important secondary meanings, its usage (illustrated by sample sentences using the word) and it is often useful to know the roots of the word. Dilip Oak’s Academy has provided two very useful aids for learning and revising these various aspects. Described below is how you can use them both at home and outside.

One of the most important aspects of preparing for reading comprehension in the GRE is preliminary reading – that is, reading to be done before you start tackling GRE RC passages in order to prepare you for the challenges that those passages will throw up.

One challenge that you will face on Reading Comprehension passages is that they tend to be about unfamiliar topics and concepts; and talk about unfamiliar terms and fields. They use difficult phrasing and vocabulary, and complicated sentence structure. The only way to get used to the level of complexity you will find in GRE passages is to read widely.
