### Hints for Math

- The Mathematics Test is in two booklets. Each part has 25 questions. The total time for taking the Mathematics Test is 90 minutes.
- For Part I, a calculator (the Casio fx-260) will be provided for your use. However, you are not required to use it. If you plan to use the calculator, become familiar with its operations before you take the test. Basic directions for the calculator are provided here (page 14) and on the actual test.
- Ten questions (seven on Part 1 and three on Part 11) on the Mathematics Test are not multiple choice. These are not the most difficult questions on the test. You should become familiar with the methods of recording your answers for these alternate-format questions (standard grid and coordinate plane grid).
- On the coordinate plane grid, make sure that you fill in only one circle to represent your answer. If you fill in more than one circle on the graph, your response will be marked as incorrect.
- You will be provided with a page of formulas at the front of the Mathematics Test booklets. Those formulas are also printed here (page 14) for your convenience. Become familiar with what is included on this page in advance of the test so that you will be able to find information more quickly during the test. You do not have to memorize the formulas.
- Some questions will provide you with more information than you need to answer them correctly. Use only the data that are relevant to the particular question.
- Some multiple-choice questions may not contain enough information to answer the question. In that case, the correct response is "Not enough information is given."
- When you obtain an answer, take a moment to determine whether your answer makes sense given the parameters of the problem. For example, if your calculation indicates that a 1-pound bag of carrots will cost $25, you should check your work for errors because $25 is not a reasonable price for this item.
- Use your personal experience to solve the problems. The settings used for the problems in the Mathematics test are usually realistic. For example, in a test question that requires you to compute weekly earnings, ask yourself, "How would I calculate my weekly earnings?"
- In diagrams, do not assume that lines are parallel or perpendicular unless the problem gives you that information in either words or symbols. This rule is true even when the lines look parallel or perpendicular.
