Preparing for your ACT exam with practice tests is a great approach. The benefits of using sample ACT test questions include:

  • Becoming comfortable with the test format – The ACT, like most standardized tests, has its own unique format. As you take more and more sample ACT tests, you will begin to see a pattern in the way the questions are written. Once the actual test day comes, you will feel comfortable and have no surprises, giving you the opportunity to succeed.
  • Improving your pace – Each section of the ACT test is timed. To do well on the exam, you need to keep a strong, steady pace going. Use our free ACT online prep to practice taking the exam in a timed format to help improve your speed and decision making on the ultimate test day.
  • Helping improve your ability to solve problems – Standardized tests measure your ability to solve problems, not just memorize information. To do well on the ACT test (especially the math section) you will need to have strong problem-solving capabilities. When you take our sample ACT questions, pay special attention to the answer rationales presented in your score report to help improve your problem-solving abilities.
  • Focusing your study time – One of the biggest advantages to taking sample tests is learning what you are good at and what you are weak at. You can then concentrate your study time on your weakest areas.
