Areas Covered: Any of the Quantitative Reasoning cover the same mix
of arithmetic, algebra, and geometry as Problem Solving questions.
Quantitative Comparison directions are similar to the following.
The “Notes” are the same as for Problem Solving questions:
Directions: Each of the following questions consists of two quantities, one in
Column A and one in Column B. You are to compare the two quantities and
choose whether
(A) the quantity in Column A is greater;
(B) the quantity in Column B is greater;
(C) the quantities are equal;
(D) the relationship cannot be determined from the information given.
Common Information: In a question, information concerning one or both of
the quantities to be compared is centered above the two columns. A symbol
that appears in both columns represents the same thing in Column A as it
does in Column B.
Notes:
- All number used are real numbers.
- All figures lie on a plane unless otherwise indicated.
- All angle measures are positive.
- All lines shown as straight are straight. Lines that appear jagged can also
be assumed to be straight (lines can look somewhat jagged on the computer
screen).
- Figures are intended to provide useful information for answering the
questions.
However, except where a figure is accompanied by a “Note”
stating that the figure is drawn to scale, solve the problem using your
knowledge of mathematics, not by visual measurement or estimation.
In this book, the four choices
For answering Quantitative
Comparisons are labeled (A),
(B), (C), and (D). On the
computer-based GRE, they
won’t be lettered, but they’re
always listed in the same order
as they are here.
Other Key Facts
There are only four answer choices, and they’re the same for all Quantitative
Comparison questions.
- All information centered above the columns applies to both columns. Some Quantitative
Comparisons will include centered information; others won’t.
- The same variable (such as x) in both columns signifies the same value in both
expressions.
- As in Problem Solving questions, figures are not necessarily drawn to scale, so
don’t rely solely on the visual appearance of a figure to make a comparison.
- Quantitative Comparisons are not inherently easier or tougher than Problem
Solving questions, and their level of difficulty and complexity varies widely, as
determined by the correctness of your responses to previous questions.
- You’ll make fewer calculations and solve fewer equations for Quantitative Comparison
questions than for Problem Solving questions. What’s being tested here is
mainly your ability to recognize and understand principles, not your ability to
work step-by-step toward a solution.
- Calculators are prohibited, but scratch paper is provided.
