Most of the exams are presented in an adaptive test format.
Adaptive testing gives a more accurate assessment of the test taker s knowledge.
Experts claim that traditional multiple-choice tests often present too many questions and do not accurately measure the student s ability to answer difficult questions. Adaptive testing adjusts itself to the test taker s level of knowledge. It discovers the level, on a scale of easy to difficult, at which the person begins to encounter challenging questions. A score is derived for that level. The test first presents a question of medium difficulty.
