Note to Test Takers:
Keep this practice book until you receive your score report.
This book contains important information about content specifications and scoring.
This practice book and the interpretive information included in it are appropriate
for individuals taking the Mathematics Test (Rescaled) after October 1, 2001. The
GRE Mathematics Test will be rescaled effective October 2001 and renamed “Math-
ematics Test (Rescaled)”; the content of the test will not change. Although the
range of scores for the Mathematics Test (Rescaled) will continue to extend from
200 to 990, scores earned on the test after October 2001 should not be compared
to scores earned earlier.
The primary reason for rescaling the Mathematics Test is to make the test scores
more useful for admissions committees and other score users by spreading out high-
ability examinees on the score scale. The scores of the Mathematics Test population
have increased substantially since the test was first scaled in 1952, and
an increasingly large percentage of individuals each year have been earning 990, the
highest possible score on the scale. Based on recent interpretive data (individuals
who were tested between October 1996 and October 1999), 18 percent of the
examinees received 990 on the test (in other words, the percentage of test takers
scoring below 990 was 82). The scale of the new Mathematics Test (Rescaled) will
enable admissions committees and other score users to distinguish among high-
scoring examinees, something the former scale was no longer able to do.

MATHEMATICS TEST (RESCALED)
PRACTICE BOOK
Purpose of the
GRE Subject Tests
The GRE Subject Tests are designed to help graduate
school admission committees and fellowship sponsors
assess the qualifications of applicants in specific fields
of study. The tests also provide you with an assessment
of your own qualifications.
Scores on the tests are intended to indicate knowl-
edge of the subject matter emphasized in many under-
graduate programs as preparation for graduate study.
Because past achievement is usually a good indicator of
future performance, the scores are helpful in predicting
success in graduate study. Because the tests are stan-
dardized, the test scores permit comparison of students
from different institutions with different undergraduate
programs. For some Subject Tests, subscores are pro-
vided in addition to the total score; these subscores
indicate the strengths and weaknesses of your prepara-
tion, and they may help you plan future studies.
The GRE Board recommends that scores on the
Subject Tests be considered in conjunction with other
relevant information about applicants. Because numer-
ous factors influence success in graduate school,
reliance on a single measure to predict success is not
advisable. Other indicators of competence typically
include undergraduate transcripts showing courses
taken and grades earned, letters of recommendation,
the GRE Writing Assessment score, and GRE General
Test scores. For information about the appropriate use
of GRE scores, write to GRE Program, Educational
Testing Service, Mail Stop 57-L, Princeton, NJ 08541,
or visit our Web site at www.gre.org/codelst.html.
Development of the
Subject Tests
Each new edition of a Subject Test is developed by a
committee of examiners composed of professors in the
subject who are on undergraduate and graduate facul-
ties in different types of institutions and in different
regions of the United States and Canada. In selecting
members for each committee, the GRE Program seeks
the advice of the appropriate professional associations
in the subject.
The content and scope of each test are specified
and reviewed periodically by the committee of exam-
iners. Test questions are written by the committee and
by other faculty who are also subject-matter specialists
and by subject-matter specialists at ETS. All questions
proposed for the test are reviewed by the committee
and revised as necessary. The accepted questions are
assembled into a test in accordance with the content
specifications developed by the committee to ensure
adequate coverage of the various aspects of the field
and, at the same time, to prevent overemphasis on any
single topic. The entire test is then reviewed and
approved by the committee.

MATHEMATICS TEST (RESCALED)
PRACTICE BOOK
Subject-matter and measurement specialists on the
ETS staff assist the committee, providing information
and advice about methods of test construction and
helping to prepare the questions and assemble the test.
In addition, each test question is reviewed to eliminate
language, symbols, or content considered potentially
offensive, inappropriate for major subgroups of the test-
taking population, or likely to perpetuate any negative
attitude that may be conveyed to these subgroups. The
test as a whole is also reviewed to ensure that the test
questions, where applicable, include an appropriate
balance of people in different groups and different roles.
Because of the diversity of undergraduate curricula,
it is not possible for a single test to cover all the
material you may have studied. The examiners, there-
fore, select questions that test the basic knowledge and
skills most important for successful graduate study in
the particular field. The committee keeps the test
up-to-date by regularly developing new editions and
revising existing editions. In this way, the test content
changes steadily but gradually, much like most cur-
ricula. In addition, curriculum surveys are conducted
periodically to ensure that the content of a test
reflects what is currently being taught in the under-
graduate curriculum.
After a new edition of a Subject Test is first admin-
istered, examinees’ responses to each test question are
analyzed in a variety of ways to determine whether
each question functioned as expected. These analyses
may reveal that a question is ambiguous, requires
knowledge beyond the scope of the test, or is inappro-
priate for the total group or a particular subgroup of
examinees taking the test. Answers to such questions
are not used in computing scores.
Following this analysis, the new test edition is
equated to an existing test edition. In the equating
process, statistical methods are used to assess the
difficulty of the new test. Then scores are adjusted so
that examinees who took a difficult edition of the test
are not penalized, and examinees who took an easier
edition of the test do not have an advantage. Varia-
tions in the number of questions in the different
editions of the test are also taken into account in
this process.
Scores on the Subject Tests are reported as three-
digit scaled scores with the third digit always zero.
The maximum possible range for all Subject Test total
scores is from 200 to 990. The actual range of scores for
a particular Subject Test, however, may be smaller. The
maximum possible range of Subject Test subscores is
20 to 99; however, the actual range of subscores for
any test or test edition may be smaller. Subject Test
score interpretive information is provided in Interpret-
ing Your GRE Scores, which you will receive with
your GRE score report, and on the GRE Web site at
www.gre.org/codelst.html.
Content of the 
Mathematics Test (Rescaled)
The test consists of 66 multiple-choice questions,
drawn from courses commonly offered at the under-
graduate level. Although the Mathematics Test has
been rescaled, the content of the test has not changed.
Approximately 50 percent of the questions involve
calculus and its applications —subject matter that can
be assumed to be common to the backgrounds of
almost all mathematics majors. About 25 percent of
the questions in the test are in elementary algebra,
linear algebra, abstract algebra, and number theory.
The remaining questions deal with other areas of
mathematics currently studied by undergraduates in
many institutions.
The following content descriptions may assist
students in preparing for the test. The percentages
given are estimates; actual percentages will vary
somewhat from one edition of the test to another.
Calculus — 50%
Material learned in the usual sequence of elementary
calculus courses — differential and integral calculus
of one and of several variables — including calculus-
based applications and connections with coordinate
geometry, trigonometry, differential equations, and
other branches of mathematics
Algebra — 25%
Elementary algebra: basic algebraic techniques and
manipulations acquired in high school and used
throughout mathematics

MATHEMATICS TEST (RESCALED)
PRACTICE BOOK
Linear algebra: matrix algebra, systems of linear
equations, vector spaces, linear transformations, char-
acteristic polynomials, eigenvalues and eigenvectors
Abstract algebra and number theory: elementary
topics from group theory, the theory of rings and
modules, field theory, and number theory
Additional Topics — 25%
Introductory real analysis: sequences and series of
numbers and functions, continuity, differentiability
and integrability, elementary topology of R and R
n
Discrete mathematics: logic, set theory, combina-
torics, graph theory, and algorithms
Other topics: general topology, geometry, complex
variables, probability and statistics, and numerical
analysis
The above descriptions of topics covered in the test
should not be considered exhaustive; it is necessary to
understand many other related concepts. Prospective
test takers should be aware that questions requiring no
more than a good precalculus background may be quite
challenging; some of these questions turn out to be
among the most difficult questions on the test. In
general, the questions are intended not only to test
recall of information, but also to assess the test taker’s
understanding of fundamental concepts and the ability
to apply these concepts in various situations.
Preparing for a Subject Test
GRE Subject Test questions are designed to measure
skills and knowledge gained over a long period of time.
Although you might increase your scores to some extent
through preparation a few weeks or months before you
take the test, last minute cramming is unlikely to be of
further help. The following information may be helpful.
n A general review of your college courses is
probably the best preparation for the test. How-
ever, the test covers a broad range of subject
matter, and no one is expected to be familiar
with the content of every question.
n Use this practice book to become familiar with
the types of questions in the GRE Mathematics
Test (Rescaled), paying special attention to the
directions. If you thoroughly understand the
directions before you take the test, you will
have more time during the test to focus on
the questions themselves.
Test-Taking Strategies
The questions in the practice test in this book illus-
trate the types of multiple-choice questions in the test.
When you take the test, you will mark your answers on
a separate machine-scorable answer sheet. Total testing
time is two hours and fifty minutes; there are no
separately timed sections. Following are some general
test-taking strategies you may want to consider.
n Read the test directions carefully, and work as
rapidly as you can without being careless. For
each question, choose the best answer from the
available options.
n All questions are of equal value; do not waste
time pondering individual questions you find
extremely difficult or unfamiliar.
n You may want to work through the test quite
rapidly, first answering only the questions about
which you feel confident, then going back and
answering questions that require more thought,
and concluding with the most difficult questions
if there is time.
n If you decide to change an answer, make sure
you completely erase it and fill in the oval
corresponding to your desired answer.
n Questions for which you mark no answer or more
than one answer are not counted in scoring.
n As a correction for haphazard guessing, one-
fourth of the number of questions you answer
incorrectly is subtracted from the number of
questions you answer correctly. It is improbable
that mere guessing will improve your score
significantly; it may even lower your score.
If, however, you are not certain of the correct
answer but have some knowledge of the question
and are able to eliminate one or more of the
answer choices, your chance of getting the right
answer is improved, and it may be to your advan-
tage to answer the question.
