Quantitative Comparison 
Quantitative Comparison questions ask you to compare two quantities in two columns and determine whether one is
greater, they are equal, or if there is not enough information to determine the relationship between the two quantities.

Some questions include additional information that is centered above the two columns that concerns one or both of the
quantities. These questions may not require that you solve for every value. Instead, you are assessing the relationship
between the expressions or quantities in the two columns. There is only one correct answer for each Quantitative
Comparison question. Below is an example.
xy
_ = 3 
_4
A Quantity A is greater 
B Quantity B is greater 
C The two quantities are equal 
Quantity A 
Quantity B
D The relationship cannot be determined

In this sample problem, you are given additional information to consider when analyzing the relationship between Column
A and B:
xy
 = 3 
4. This given should be applied to both quantities before you make a comparison. Remember, you are not
necessarily looking for a value, but rather an understanding of how the two columns relate. In this case the answer will
be A.
Problem Solving
Problem Solving questions are the catch-
all questions on the GRE. These questions draw from any of the math content
areas and are presented as either word problems, finding the angle of a geometric figure, or pure calculations of algebraic
expressions. You will have access to the on-
screen calculator to help you with any necessary calculations, though some
of the questions will require scratch paper to work out the expression. Unlike the Quantitative Comparison questions,
your answer for Problem Solving questions will be a value or expression.
Problem Solving questions have a variety of options when it comes to answer choices and there may be more than one
correct response to the question. You will have to select 
all
of the correct answer choices in order to receive credit for
the problem. 
What is the value of 
__ the

expression?
(2 √ 2 )( √ 6 ) + 2 √ 3 
A 20 _
B 6 √ 8

C 6 √ 3

D 4 √ 2 + 2
_
√ 3 
E 
12 √ 3 
For this problem, you will need to solve the equation and select the corresponding answer choice. In this case the correct
answer is C.
