各位探讨一下如果时间不够的做题策略。

欢迎CD的大牛们指点，如果我已经铁定做不完了，比如我只剩下一分钟了，但是还有3个题目没做，我是应该拼RP乱选，还是宁愿强行交卷也不乱作。哪种更好一些？希望大家来积极探讨。

非常感谢楼上那位，我把它贴过来了。。。
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:

Skipped questions can hurt your score really badly – even worse than you think.
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.

恩，楼上的我在曼哈顿GMAT上面也看到别人TUTOR的详细说明

但是乱选的时间是不是也不应该少于15秒，我上次考做得很慢，有七道题没做完，那时还有一分钟，我就是乱选，结果后果也很严重
