如果时间不够，最后几题是空着不做还是乱选更好？短暂告别CD前再做点贡献

楼主最近分手GMAT，在verbal部分4题完全没做，Q只有50的情况下依然拿了750。有同学说我不应该空着，应该瞎选，这样扣分比较低。看到同学的留言，楼主很懊悔，然后看了很多很多的不同的英文论坛，很多人都说“you must finish the test", "you must never leave questions unanswered"之类的话。楼主越看越不爽，然后找到了一个GMAC的官方说法。

帖子是GMAC官网2009年9月份发布的，虽然有点老了，但是楼主觉得可以做参考。

Based on an analysis of thousands of actual GMAT records, the question of whether to guess or leave questions blank (at the end) depends on the number of items you have left, the section you are on (Verbal or Quantitative), and your relative ability. Here is how it breaks down:

• If you only have 1 or 2 items left in either section, it doesn’t make much difference if you guess or omit the question. You should finish the item you are on to the best of your ability and not worry about the others.
• If you are on the Verbal section, it doesn’t make much difference if you guess when you have up to about 5 questions left. You should finish the item you are on to the best of your ability and not worry about the others.
• In the Quantitative section, your odds improve if you guess and complete all the questions rather leave the final questions unanswered. After all, there are fewer questions in this section, so each item left blank in this section comprises a higher proportion of the test than in the verbal section. Guess as smartly as you can, but guess nonetheless—do not leave items blank.
• If you have an idea what your relative ability is ahead of time (i.e., you’ve taken a practice test or diagnostic test), then your guess versus omit strategy differs based on where you think you would fall. If your scores tend to be relatively low on the section, leaving the questions blank may actually result in a higher score than getting even the easy questions wrong by guessing. If you are near the top of the scale, you have farther to fall if you omit the items and therefore you should guess. Low ability—omit; high ability—guess; medium ability—see above.

所以楼主最后几题其实空着不做和乱做最后分数可能大概就差个10分，但是！！！！！！！！！！乱猜的话可能会猜对，这时候可能就是20分的差别的。所以moral of the story is: you must finish the exam!!!!!!!!!!

楼主惨痛的教训！！！！！！！！！
