Do you get stuck on GRE Quantitative Comparison (QC) questions? If so, then you’ve come to the right place. In this blog, we will discuss general tips to solve Quantitative Comparison (QC) questions that are tested in GRE – Quantitative Reasoning section.

A Quantitative Comparison question will look like this:

Directions: Compare Quantity A and Quantity B, using additional information centered above the two quantities if such information is given, and select one of the following four answer choices:

(A) Quantity A is greater.
(B) Quantity B is greater.
(C) The two quantities are equal.
(D) The relationship cannot be determined from the information given.

A symbol that appears more than once in a question has the same meaning throughout the question.

Let’s look at an example of a QC question.

x is a non-zero number

Quantity A                           Quantity B
x2                                              x3

(A) Quantity A is greater.
(B) Quantity B is greater.
(C) The two quantities are equal.
(D) The relationship cannot be determined from the information given.

Quantity A is greater means that for any and every possible case, Quantity A will always be greater than Quantity B.

Quantity B is greater means that for any and every possible case, Quantity B will always be greater than Quantity A.

The two quantities are equal means that for any and every possible case, the two quantities will always be equal.

The relationship cannot be determined from the information given: This will be true when more than one relationship stated above is true.

## QC Tip #1

Typically, there are 6 – 8 Quantitative Comparison (QC) questions tested in each of the math sections. And the answer choices that appear in these questions are always the same. So, it is recommended that you get familiar with or remember the answer choices.  This means that knowing the answer choices will save the time spent on each of QC question.

## QC Tip #2

QC questions are relatively easier than other type of questions tested, and require less time to solve. Therefore, you should allot approximately 45 seconds to 90 seconds to each QC question.

## QC Tip #3

Most of the Quantitative Comparison questions do not require complete computation. You don’t have to solve a question completely, you just need to establish how 2 values compare against each other. So try to minimize your calculation wherever possible.

## QC Tip #4

Geometric figures are not accurate and drawn to scale in QC questions unless and otherwise stated. Therefore, you should reason your answers well rather than comparing the two quantities either by measurement or by the way the figure looks like.

## QC Tip #5

The most important thing to keep in mind is that, in a particular section, all questions carry equal weight. This means that the questions that are easy to solve or require less time are worth the same as the complex or difficult ones. So, it is better to mark a difficult question and revisit later.

So, GRE-takers, now you know what you have to keep in mind while solving Quantitative Comparison questions.
