我没有要战兔大啦，这个先澄清，只是我觉得测试GMATPrep跟真实考试 应该还是有一段差距 我之前有在第5722篇分享在美国论坛上面看到的一篇文章，在其他论坛 也看到其他的人分享类似的资讯，还特别声明已经跟GMAC的首席统计师 确认过了，数据跟结论都没有问题，我下次找到再来分享 我只能说，给我选，我当然相信出题的官方机构的统计师啊 原文连结在这里: http://tinyurl.com/yl9fur5 全文如下，是美国的Kaplan补习班的Assistant Director写的，他本身 是哈佛大学毕业，也兼任补习班的讲师: Andrew is the Assistant Director GMAT & GRE Programs at Kaplan.

Last Thursday I had the pleasure of attending the GMAC Test Prep Summit and hearing about the GMAT from GMAC's VP of Research, himself a senior psychometrician (“psychometrician” = GMAT wizard). Over the course of the day I picked up a lot of invaluable nuggets about how the test is scored, and over the next weeks I'll share these nuggets with you. Today's topic: skipped or omitted questions. You can't really “skip” questions on the GMAT, but if you run out of time you may leave some unanswered at the end and those questions are referred to as skipped or omitted questions. A few Key Takeaways: 1. Skipped questions can hurt your score really badly – even worse than you think. 2. It's complex to answer how much a skipped question hurts your score, but given Key Takeaway #1 above, the complexity doesn't matter much from your perspective. Skipped questions hurt your score more when you are scoring high. Here is real data, shared by GMAC: * If your percentile score is otherwise 70th, and you skip one question, your score drops to 65th percentile. * If your percentile score is otherwise 70th, and you skip three questions, your score drops to 55th percentile. The exact science is complex. In fact, these figures were presented as empirical results – implying that these results are not transparent in the scoring algorithm, but that rather, they must be inferred after the fact from test-takers scores. Forget about that. Instead, meditate on those two bullet points. Five percentile points for one skipped question. Given that the effect is pronounced at higher scores, I'd wager that if you're dancing near a 700 level performance on one section, around 90th percentile, then omitting one question could drop you a good 7 percentile points. Your weeks, months of GMAT prep that you've put in (around 100 hours for those scoring 700+) to raise the ceiling of your performance could be thrown away simply by mismanaging your last few seconds. Lessons: * Don't omit any questions. * While it's generally not to your advantage to finish very early, it would be much, much better to finish a whopping 60 seconds early, if that's what you have to do to make sure you don't omit any questions. More nuggets coming up. They are equally earth-shattering, so stay tuned. ※ 引述《tootoobenee (A级垂耳兔)》之铭言： : 我是认为影响不大,基本上经过测试结果发现, 第二个加分区和完工比例比较有关系, : 基本上littlelay完工比例已经接近98%, 基本上不太会被扣分. : 以上纯属个人测试PP模考系统经验,供参考. : ※ 引述《acapollo (acapollo)》之铭言： : : 这个真的太可惜了，我猜想你本来可以破 700的，大概因为没做完被 : : 扣了至少7个 percentile : : 其实时间不太够的时候有一个 trick，就是最后一题，先不要看题目， : : 直接选一个答案 ，通常是建议选CDE其中一个（机率比较高），然后 : : 再仔细看题目作答，有时间就改，没时间就算了，写到最后一题不必 : : 按 Next，只要有选到任何一个选项，就算是有作答，就不会被扣分 : : 这个是美国的补习班教的 trick，不知道老方跟老莫他们有没有教， : : 大家可以参考一下 --
