### 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

### 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.

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.

- 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.
