The entire GMAT® quantitative part of the exam takes place in one section of the test. This section contains
37 questions and must be completed in 75 minutes. Therefore, the test taker can spend about two minutes
per question, on average. The questions in this section consist of two different multiple-choice formats: prob-
lem solving and data sufficiency. Each type of question has five possible choices for answers. These questions
test a person’s knowledge of mathematical concepts and their applications, along with thinking and reason-
ing skills. Examinees will be asked to recall the mathematics that they learned in middle school and high
school and apply these skills in an advanced manner for the questions on the test. Although scrap paper is
allowed, the use of calculators is prohibited on the GMAT exam.
Since the Quantitative section is only administered as a CAT, this section will be taken on a computer.
As each person takes the exam, the computer randomly generates the sequence of questions administered
based on the participant’s ability. The test begins with a question of average difficulty. If the question is
answered correctly, points are added to the score and a more difficult question follows. If the question is
answered incorrectly, there is no penalty, but an easier question follows. Keep in mind that harder questions
carry more weight and will result in a higher score. Because of the CAT format, each question must be
answered and confirmed before proceeding to the next question. Since randomly guessing an incorrect answer

will lower your score, making an educated guess by eliminating one or more of the answer choices should
result in a better score. Your score is based on both the number of questions you answer and the level of dif-
ficulty of the questions; the more difficult questions you answer, the better.
Even though the Quantitative section is administered on a computer, minimal computing skills are nec-
essary. Free GMAT tutorials can be downloaded from various Internet sites and taken ahead of time. The test-
ing site also offers a tutorial that can be completed immediately before commencing the test. These skills, such
as using the mouse and the HELP feature, should be practiced before beginning the test. Once you start a par-
ticular section of the exam, the clock cannot be stopped. Time spent asking for help will be counted in the
total time for that particular section.
The quantitative portion will not test how well you recall a lot of facts and figures; instead, it will test
how well you use your existing knowledge of math and how well you apply it to various situations. In addi-


tion, this section of the test will not evaluate your personality, work ethic, or ability to work with others.
Although the problems may seem difficult at times, they will not be assessing the undergraduate work you
may have completed in college or any particular course you may have taken; the math will be high school level.
Even though the test is used as a precursor for business school, the questions will not require knowledge of
business-related skills.
This section of the test contains a number of trial questions that are being field-tested for future use.
These particular questions will not be counted toward your total score; however, the actual questions are not
distinguished from the trial questions. Do your best on all of the questions and treat them as if they all count.

mation to answer the initial question. If you are asked for the value of a quantity, the information is suffi-
cient when it is possible to determine only one value for the quantity. The five possible answer choices are as
follows:
a. Statement (1), BY ITSELF, will suffice to solve the problem, but NOT statement (2) by itself.
b. Statement (2), BY ITSELF, will suffice to solve the problem, but NOT statement (1) by itself.
c. The problem can be solved using statement (1) and statement (2) TOGETHER, but not ONLY
statement (1) or statement (2).
d. The problem can be solved using EITHER statement (1) only or statement (2) only.
e. The problem CANNOT be solved using statement (1) and statement (2) TOGETHER.
The numbers used are real numbers. If a figure accompanies a question, the figure will be drawn to scale
according to the original question or information, but it will not necessarily be consistent with the infor-
mation given in statements (1) and (2).
