GRE Test Structure : Quantitative Ability
The quantitative section consists of 28 questions, You have 45 minutes to attemp these questions:
- 14 quantitative comparision quesitons.
- 10 discrete quantitative questions ( another name for standard multiple-choice questions)
- 4 data interpretation questions
In order to answer these questions, you need to know arithmetic, some very elementary algebra, and a little geomatry. Most of this material you learned in elementary and middle school. You do not need to know any advanced mathematics. The questions are intended to determine if you have a basic knowledge of elementary mathematics, and if you have the ability to reason clearly.
Quantitative Comparison Questions:
Of the 28 mathematics questions on the GRE, half of them (14) are what is know as quantitative comparisons. It is very likely that you have not seen such a question since you were in high school preparing for the SAT I; If you didn't have to take the SAT I, it is possible that you have never ever seen a quantitative comparison. Therefore, read the following instructions very carefully.
In these questions there are two questions, one in column A and one in column B, and it is your job to compare them. For these problems there are only four possible answers.
The Quantity in column A is greater.
The Quantity in Column B is greater.
The two quantities are equal; and
The relationship cannot be determined from the information given.
Discrete Quantitative Questions:
Of the 28 mathematics questions on the GRE, 10 are standard multiple-choice questions, what the ETS calls discrete quantitative questions. The way to answer such a question is to do the necessary work, get the solution, and then look at five choices to find your answer.
Data Interpretation Questions:
Four of the questions in the quantitative section are data interpretation questions. There are always two questions based on one set of data, and later in the section, two more questions based on a second set of data. As you might guess from time their name, these questions are based on information provided in graphs, tables, or charts. The questions test your ability to interpret the data that have been provided. You will either have to do a calculation or make an inference from the given data.
