Test Tips

An actual ACT Mathematics Test contains 60 questions to be answered in 60 minutes.

  • Read each question carefully to make sure you understand the type of answer required.
  • If you choose to use a calculator, be sure it is permitted, is working on test day, and has reliable batteries.
  • Use your calculator wisely.
  • Solve the problem.
  • Locate your solution among the answer choices.
  • Make sure you answer the question asked.
  • Make sure your answer is reasonable.
  • Check your work.

Calculator Tips

  • Review the latest information on permitted and prohibited calculators.
  • You are not required to use a calculator. All the problems can be solved without a calculator.
  • If you regularly use a calculator in your mathematics work, use one you're familiar with when you take the mathematics test. Using a more powerful, but unfamiliar, calculator is not likely to give you an advantage over using the kind you normally use.
