All questions in the Math Level 1 and Math Level 2 Tests are multiple-choice questions in which you are asked to choose the BEST response from the five choices offered. The directions for the tests are below:
Directions: For each of the following problems, decide which is the BEST of the choices given. If the exact numerical value is not one of the choices, select the choice that best approximates this value. Then fill in the corresponding oval on the answer sheet.
Notes: 1. A scientific or graphing calculator will be necessary for answering some (but not all) of the questions in this test. For each question you will have to decide whether or not you should use a calculator. 2. Level 1: The only angle measure used on this test is degree measure. Make sure your calculator is in the degree mode. Level 2: For some questions in this test you may have to decide whether your calculator should be in the radian mode or the degree mode. 3. Figures that accompany problems in this test are intended to provide information useful in solving the problems. They are drawn as accurately as possible EXCEPT when it is stated in a specific problem that its figure is not drawn to scale. All figures lie in a plane unless otherwise indicated. 4. Unless otherwise specified, the domain of any function f is assumed to be the set of all real numbers x for which f (x) is a real number. The range of f is assumed to be the set of all real numbers f (x), where x is in the domain of f. 5. Reference information that may be useful in answering the questions in this test can be found below.
Reference Information. The following information is for your reference in answering some of the questions in this test.
