Some questions on these tests cannot be solved without a scienti? c or a graphing calculator. You do not need to use a calculator to solve every question, but it is important to know when and how to use one. If you take these tests without a calculator, you will be at a disadvantage.

  We recommend the use of a graphing calculator over a scienti? c calculator because a graphing calculator may provide an advantage on some questions.

  You may not use a calculator for other Subject Tests and must put it away when not taking a mathematics test.

  For 50–60 percent of the questions on Level 1 and 35–45 percent of the questions on Level 2, there is no advantage, perhaps even a disadvantage, to using a calculator. For 40–50 percent of the questions on Level 1 and 55–65 percent of the questions on Level 2, a calculator may be useful or necessary.

  What Type of Calculator Should I Bring?

  Bring a calculator that you are used to using. It may be a scienti? c or a graphing calculator. If you’re comfortable with both a scienti? c and a graphing calculator, bring a graphing calculator.

  Verify that your calculator is in good working condition before you take the test. You may bring batteries and a backup calculator to the test center.

  No substitute calculators or batteries will be available at the test center. Students may not share calculators.

  If your calculator malfunctions during the Level 1 or Level 2 Tests and you do not have a backup calculator, you must tell your test supervisor when the malfunction occurs in order to cancel scores on these tests only.
