The Quantitative Section is easy for
most students. However, to get perfect score is not as easy as you
originally think. The objective of our GMAT
Math Review is to help you obtain PERFECT
score (99th) on the math section. We are very proud of the
results that 96% of our customers got perfect score on Math
Section.
Some features of our math course include:
-
Includes the basic math concepts and
a comprehensive review of Arithmetic, Algebra, and
Geometry. A specific math book is not necessary for a more
detailed discussion.
-
Examples of question in each
difficult level. You will develop a great understanding of how a
difficult question can be.
-
Covers easy-to-use strategies to
tackle the trick questions in Data Sufficiency.
-
Addresses Permutation, Probability,
Standard Deviation and other higher-level topics. You won't feel
lost on the test day.
-
Special chapter on Word Problem.
Word is no longer a problem for you.

Back to Top
After a
5-minute break, you are assigned to the Quantitative section, which consists
of 37 multiple-choice questions. About two-thirds of them are
problem-solving questions. A sample problem-solving question looks like
this:
Example: If m is an odd integer, which one of the following is an even
integer?
A) 
(B)
(C) 
(D) 
(E)
The other
one-thirds is the Data Sufficiency question. Unlike the problem-solving
questions, the data sufficiency doesn’t require you to work out a solution
to the presented question. Instead, it expects you to determine whether one
or two conditions are sufficient to solve the presented questions.
The GMAT math section doesn’t test your specific knowledge in
mathematics. Rather, it tests your problem solving ability. Therefore,
calculus or another advanced math topic is never covered on GMAT math. The
high school math knowledge is sufficient to answer a typical GMAT math
question. Picking up the correct answer, however, is not as easy as its
knowledge base. As we said, only the basic math concepts are chosen so that
everyone taking GMAT is put on a fair arena. To make the test effective, the
test writer should design questions that some answers correctly while other
answers incorrectly. The best solution is to create complex questions or
questions with numerous tricks.
How to use GMAT Math Review
We divide this course into five chapters, the first three of
which are the comprehensive review of basic math concepts, including
arithmetic, algebra, and geometry, the fourth is exclusively to draw on the
difficult word problems, and the final is to cover the other part of the
quantitative section--data sufficiency. Even you do not meet any problem in
the math concepts, we encourage you to pay attention to the example
questions in each section, since each example represents the most common
question you will encounter in the real test.
General
Math Strategies: Substitution
Substitution, also known as plug-in, is one of the most
effective strategies for solving complicated math questions. It is a method
in which we plug numbers that fit the question’s parameters into the answer
choices, and then determine which one is the best answer. In most cases, you
have to plug in two different numbers before you eliminate four choices.
The substitution method is also very helpful for double
checking your answers. Since you have nearly two minutes for each question,
you won’t have sufficient time to do formal formula or calculating. The
plug-in is a perfect solution. The numbers you choose for substitution
should have the properties given in the problems. For example, if the
question asks for an even integer, you should insert integer, and even
integer.
Example:
If m is an odd integer, which one of the following is an even integer?
(A)
(B)
(C)
(D)
(E)
Solution
 is
an odd integer, so we choose an odd integer for m, say 3, and plug it into
each answer choice.
Choice A:  ,
which is an odd integer, therefore, A is incorrect.
Choice B:  .
1.5 is not an integer, let alone even integer.
Choice C:  ,
which is not an even integer, either.
Choice D:  ,
which is an odd integer. Eliminate this choice.
Choice E:  .
12 is an even integer. E is correct.
Therefore, the correct answer is E.
