MATHEMATICS TEST SAMPLE QUESTIONS The following questions illustrate the range of the test in terms of abilities measured, the disciplines covered, and the difficulty of the questions posed They should not, however, be considered representative of the entire scope of the test in either content or difficulty An answer key follows the questions A student is given an exam consisting of essay questions divided into groups of questions each The student is required to select a set of questions to answer, including at least question from each of the groups How many sets of questions satisfy this requirement?
