as of the october 2012 administration, the test consists of 60 substantive questions. only 50 are scored; the other 10 (randomly scattered throughout the exam) are used for experimental purposes. the raw score is converted to a "scaled score" based on the measured difficulty of the version of the test taken; the scaled score is used to determine passing scores. scaled scores range between 50 and 150, with a median very close to 100.
