GMAT Tips and Strategies

Be familiar with the following directions so that you will not need to spend time reading them during the test.

The Directions for the Problem Solving Section

Solve the problem and indicate the best of the answer choices given.
Numbers: All numbers used are real numbers.
Figures: A figure accompanying a problem solving question is intended to provide information useful in solving the problem. Figures are drawn as accurately as possible. Exceptions will be clearly noted. Lines shown as straight are straight, and lines that appear jagged are also straight. The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero. All figures lie in a plane unless otherwise indicated.

The Directions for the Data Sufficiency Section

Each data sufficiency problem consists of a question and two statements, labelled (1) and (2), which contain certain data. Using these data and your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of the word counterclockwise ), decide whether the data given are sufficient for answering the question and then indicate one of the following answer choices.
  • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient
  • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
  • BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient
  • EACH statement ALONE is sufficient
  • Statements (1) and (2) TOGETHER are not sufficient

Note:  In data sufficiency problems that ask for the value of a quantity, the data given in the statements are sufficient only when it is possible to determine exactly one numerical value of the quantity.
Numbers: All numbers used are real numbers.
Figures:

  • Figures conform to the information given in the question, but will not necessarily conform to the additional information given in statements (1) and (2).
  • Lines shown as straight are straight, and lines that appear jagged are also straight.
  • The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero.
  • All figures lie in a plane unless otherwise indicated.

These are the topics that you will need to know for the GMAT Quantitative Section.

Arithmetic Review

Since you cannot use a calculator in the GMAT Test, it will be helpful to review how to perform some arithmetic operations without a calculator.



Algebra Review

Geometry Review

Extensive knowledge of theorems and the ability to construct proofs are not tested.
