There is more to improving your ACT score than your knowledge of mathematics. Preparation for the style of questions and the pace of the exam is just as critical for an optimal score. ACT allows student to take the test multiple times, The organization then takes the best score from each section of every test and creates a "superscore". The practice test help the student focus on and optimize their math score.

Math Practice Tests for the ACT provides eight full lengths tests that include 480 practice questions, with detailed explanations and level of difficulty provided for all questions. The practice tests will improve the student's familiarity with the ACT, providing the following:

• Familiarity with test format means time saved that can be applied to the test questions.
• Knowledge of test question styles minimizes confusion, saves time and improves accuracy.
• Practice test results show areas where the student needs additional review.

Students who practice the ACT are better prepared and have less stress during the test. Maximize your score through preparation.

MATHEMATICS TEST

60 Minutes—60 Questions

DIRECTIONS: Solve each problem, choose the correct answer, and then fill in the corresponding oval on your answer document.

Do not linger over problems that take too much time. Solve as many as you can; then return to the others in the time you have left for this test.

You are permitted to use a calculator on this test. You may use your calculator for any problems you choose, but some of the problems may best be done without using a calculator.

Note: Unless otherwise stated, all of the following should be assumed.

1. Illustrative figures are NOT necessarily drawn to scale.

2. Geometric figures lie in a plane.

3. The word line indicates a straight line.

4. The word average indicates arithmetic mean.
