Take this test as a practice to the GED test.
To simulate the test conditions, use the time constraints of the official GED Mathematics Test. Allow 45 minutes for Part I. You may use a calculator to answer these 25 questions. Then, give yourself 45 minutes for Part II. You should not use a calculator for these 25 questions.
Remember, on the official GED, an unanswered question is counted as incorrect, so make a good guess.
Directions: Read each of the following questions carefully and determine the best answer. Record your answers on the answer sheet for multiple-choice questions and by filling in the circles in the grids for alternative-format questions.
Note: On the GED, you are not permitted to write in the test booklet. For this test, practice by making any notes or calculations on a separate piece of paper.
