For students who spend most of their time studying from the ETS book and the on-line paper-based tests, you are probably used to seeing four Data Interpretation questions per test. On the actual test, which has twenty questions per math section, there are only three Data Interpretation questions per section, leading to a total of […]

## GRE Numeric Entry Questions

One of the most dread-inducing additions to the GRE—back when it changed in Aug. 2011—was the Numeric Entry question. The reason is apparent: instead of five answer choices to guide you, suddenly there is nothing more than a box, a big blank waiting for you to cough up one number out of millions (if not […]

## Quantitative Comparison and Manipulation

Many quantitative questions have variables in both columns. While your first instinct may be to work algebraically, this strategy is not always best. Often the fastest way to a solution is by plugging in different values to see which column is greater. Developing a sense of when to plug in and when to solve algebraically […]

## Quantitative Comparison: “The Relationship Cannot Be Determined from the Information Given” Answer Choice

The quantity in Column A is greater The quantity in Column B is greater The two quantities are equal The relationship cannot be determined from the information given Many people dread choosing answer choice (D) on Quantitative Comparison (QC) Some feel it may be conceding defeat. Others think that the GRE is trying to trick them […]

## The Basics of Data Interpretation on the GRE

Fact: within the course of each Quantitative section, you will have, on average, two sets of Data Interpretation questions. Each set will present data in some form (graph, table, etc.), and you will have two or three consecutive questions on that same data set. Why does the GRE ask Data Interpretation questions? Absolutely in […]

## GRE Data Interpretation Strategies

Helpful Tips for the GRE Data Interpretation Section If I had to count the number of questions/concerns regarding combinations or permutations, I’d have to use some pretty mighty factorials to do so. On the other hand, if I had to count the number of times students have expressed the same misgivings regarding Data Interpretation, I’d […]

## GRE Quantitative Comparison: The Devil is in the Details

Many quantitative comparison questions come with parameters. Parameters are basically a few ground rules that are listed above Column A and Column B. x is a positive integer Column A Column B The quantity in Column A is greater The quantity in Column B is greater The two quantities are equal The relationship cannot […]

Here’s the whole series of QC tips: Tip #1: Dealing with Variables Tip #2: Striving for Equality Tip #3: Logic over Algebra Tip #4: Comparing in Parts Tip #5: Estimation with a Twist In my last post, we solved the following question: A. The quantity in Column A is greater B. The quantity […]

## GRE Quantitative Comparison Tip #4 – Comparing in Parts

To set up today’s Quantitative Comparison (QC) strategy, please solve the following question: A. The quantity in Column A is greater B. The quantity in Column B is greater C. The two quantities are equal D. The relationship cannot be determined from the information given There are several different ways to solve this question. […]

## GRE Quantitative Comparison Tip #3 – Logic over Algebra

In previous posts (Tip #1 – Dealing with Variables, Tip #2: Striving for Equality), I have discussed two approaches when tackling Quantitative Comparison (QC) questions involving variables. Those approaches are: 1) Apply algebraic techniques 2) Plug in numbers In those posts, I noted that the algebraic approach is typically the faster and more reliable approach. […]
