GED Practice Test

Directions:

The Mathematics Test consists of multiple-choice questions intended to measure general mathematics skills and problem-solving ability. The questions are based on short readings that often include a graph, chart, or figure.

You should try to complete the 25 questions on the test in 45 minutes. Work carefully, but do not spend too much time on any one question. Be sure you answer every question.

Formulas you may need are listed under the Formulas link in the sidebar on the left-hand side of your screen. Only some of the questions will require you to use a formula. Not all the formulas given will be needed.

Some questions contain more information than you will need to solve the problem; other questions do not give enough information. If the question does not give enough information to solve the problem, the correct answer choice is "Not enough information is given."

Some questions require you to choose the correct form of an answer as it appears on an alternate format grid or on a coordinate plane grid. If you need help understanding these grids, click on the Alternate Grids link in the sidebar on the left-hand side of your screen.

The use of calculators is allowed for questions 1–13. If you need help using your calculator, click on the Calculator Directions link in the sidebar on the left-hand side of your screen.

When you have finished the test, click on Submit Answers to receive feedback and results. You may also choose to e-mail your results to your instructor. Click on GED Score in the sidebar on the left-hand side of your screen to determine your GED standard score.



You may use a calculator for questions 1–13.
