第五条 Do not spend too much time on any one question. .........guessing may lower your score, but not finishing the section will lower your score more.
两个Myth and Fact说明 1、误区：正确回答比答完试题更加重要 正解：If you are stumped by a question, give it your best guess and move on. If you guess incorrectly, the computer program will likely give you an easier question, which you are likely to answer correctly, and the computer will rapidly return to giving you questions matched to your ability. If you don't finish the test, your score will be reduced greatly. Failing to answer five verbal questions, for example, could reduce your score from the 91st percentile to the 77th percentile. Pacing is important.
2 误区：前10道题至关重要，所以应该花多一点时间 正解：It is ture that the computer-adaptive testing algorithm uses the first 10 questions to obtain an initial estimate of your ability; however, that is only a initial estimate. As you continue to answer questions, the algorithm self-corrects by computing an updated estimate on the basis of all the questions you have answered, and then administers items that are closely matched to this new estimate of your ability. Your final score is based on all your responses and considers the difficlty of all the questions you answered. Taking additional time on the first 10 questions will not game the system and can hurt your ability to finish the test.
