The General Educational Development (GED) Mathematics Test is divided equally into two parts:
What to expect

Expect questions that will test how well you understand and can apply the basic concepts of arithmetic (number sense, operations, statistics, probability, and data analysis), basic algebra, and informal geometry and measurement.

Expect settings that are familiar in everyday life. A grocery store, a bank, a theater, a restaurant, and a sporting event would all be familiar settings.

Expect about twothirds of the questions to refer to situations.

Expect about onethird of the questions to refer to graphs or charts.

Expect some questions to be in groups, or sets — that is, two to four questions that refer to the same situation, chart, or graph.

Expect some questions where you will have to grid in answers on an answer grid or a coordinate grid.

Expect a formulas page to refer to if necessary.

Kinds of questions
The GED Mathematics Test will test application and problemsolving skills. The questions will stress your being able to apply concepts and basic skills.
Look for problems that ask you to

Visualize

Set up an expression or equation

Estimate or approximate

Do simple calculations

Work out ratios and proportions

Apply given formulas

Use your basic knowledge

Work from the answers

Find the reasonable answer

Decide if you have enough information or need more
