我沒有要戰兔大啦，這個先澄清，只是我覺得測試GMATPrep跟真實考試應該還是有一段差距我之前有在第5722篇分享在美國論壇上面看到的一篇文章，在其他論壇也看到其他的人分享類似的資訊，還特別聲明已經跟GMAC的首席統計師確認過了，數據跟結論都沒有問題，我下次找到再來分享我只能說，給我選，我當然相信出題的官方機構的統計師啊原文連結在這里: http://tinyurl.com/yl9fur5 全文如下，是美國的Kaplan補習班的Assistant Director寫的，他本身是哈佛大學畢業，也兼任補習班的講師: 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級垂耳兔)》之銘言： : 我是認為影響不大,基本上經過測試結果發現, 第二個加分區和完工比例比較有關係, : 基本上littlelay完工比例已經接近98%, 基本上不太會被扣分. : 以上純屬個人測試PP模考系統經驗,供參考. : ※ 引述《acapollo (acapollo)》之銘言： : : 這個真的太可惜了，我猜想你本來可以破 700的，大概因為沒做完被 : : 扣了至少7個 percentile : : 其實時間不太夠的時候有一個 trick，就是最后一題，先不要看題目， : : 直接選一個答案，通常是建議選CDE其中一個（機率比較高），然后 : : 再仔細看題目作答，有時間就改，沒時間就算了，寫到最后一題不必 : : 按 Next，只要有選到任何一個選項，就算是有作答，就不會被扣分 : : 這個是美國的補習班教的 trick，不知道老方跟老莫他們有沒有教， : : 大家可以參考一下 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.32.2.176
