请问GMAT考试如果来不及,剩下的题目是乱选选完还是空着不做??

为什么我听人说,不做完空着比做错得分要高??

有没有官方说法

选完。

没做和做错目前是一样对待的（可能略有差别，但应该差别不大）。但是选完的话，你还有机会选对答案。

补充一下。没做完的处理方式有很多种，比如全部算错，或者根据现有的分数推测等等。具体用的是那种方式要看guide里到底是如何描述的。

根据以前的资料，很可能用的是proportional scoring。具体细节比较技术性，主要就是一点，就是使用proportional scoring的话，没有完成的分数普遍（高、中、低三种能力的人）要比猜题的分数低（4-5分）。但是有一种情况例外，就是如果只有一题没有完成的话，猜题反而会导致低分。注意，以上的结果是统计上的数字，就是对整个人群来说是正确的，对于各人来说每个人的情况的是不一样的。有兴趣的可以去看一下Steffen&Mill的研究。

Total, Verbal, and Quantitative Scores

Total GMAT® scores range from 200 to 800. Two-thirds of test takers score between 400 and 600.

The Verbal and Quantitative scores range from 0 to 60. Scores below 9 and above 44 for the Verbal section or below 7 and above 50 for the Quantitative section are rare. Both scores are on a fixed scale and can be compared across all GMAT® test administrations. The Verbal and Quantitative scores measure different constructs and cannot be compared to each other.

Please note that, if you do not finish in the allotted time, you will still receive scores as long as you have worked on every section. However, your scores will be calculated based upon the number of questions answered, and your score will decrease significantly with each unanswered question.

曾经有过这种情况（那时有个80%法则）。但是引入proportional scoring之后，未完成题目的得分要比猜题的得分低，鼓励你尽量做完题目。
