927,北美,辛辛苦苦准备了几个月,换来的却是无尽的悲哀。考前的两次模考,670,680。数学都是49.GWD错15-18个,算上做不完的题
数学遇到了好多机经,逻辑有几道,作文有一篇关于妇女政治权利的。
最后结果出来590(Q49,V21),瞬间石化。
想不通啊想不通,数学基本上没有不确定的,怎么出来还是这个分数。
verbal做不完,GWD和一些童鞋说没关系,不要乱点,我就没在意,剩了6道题。
而且我的第二次PREP模考也是剩下5道题。
为神马啊为神马?盼求高人指点一下啊。
作文AA考的是200学生抗议的那个,AI是学校是否要花多一些的时间来叫科技而不是人文。
数学
ds:给个抛物线的公式 f(x)=-50x^2+px+q 问f(50)是多少
(1)f(0)=0
 (2)  f(40)是最大值
LZ记得是因为这道题花的时间相对多些,最后选的C,
从1中可以得出一个关于p,q 二元一次方程,
从2中得到40是顶点也就是中线推出f(50)=f(30) 又得到一个关于p,q 二元一次方程
综合应该能得出C


别的记不住了,看到分数后大脑一片空白了

gwd说的不要乱点,没关系,是什么时候说的?前两天不是刚看见有筒子说manhattan刚和GMAC沟通过说如果做不完,惩罚会很大吗.楼主可以再搜锁一下原帖是怎么说的。现在似乎是:做不完后果也很严重!

看到GWD的视频,什么时候记不得了,还有各种童鞋的现身说法。
看来还是要提高尽量自己的能力,
在保证正确率的前提下做完题

还有个细节,有人说最后时间不多了不够做完一道题就不要点next,
因为你最后不选的那题要算错
我最后还剩不到一分钟,就没有点next, 老老实实的看最后一道阅读

下面是Manhattan 发出来的新闻 原文
Idioms, Myths and More: News from the GMACby Stacey Koprince, Manhattan GMAT Instructor
I just got back from the biennial GMAC Test Prep Summit. (Quick: what does biennial mean? Just in case you see the word in a question!) We discussed a number of very interesting things. Don’t worry – I won’t totally geek out on you – but some of what we discussed will be useful for you even if you don’t make your career in test prep.
In this article, we’re going to discuss information from the conference that is relevant to everyone taking the test right now (or soon). Most of the key bits were gleaned from the presentations of Dr. Lawrence M. Rudner, Chief Psychometrician of GMAC. All quotes and statistics throughout this article are courtesy of Larry. Keep an eye out for a future article in which we’ll dive a bit more deeply into the Next Generation GMAT, which will launch in June of 2012. (Oh – and “biennial” means “every 2 years.”)
The myths are still mythsThe earlier questions are not worth more. Accuracy is not more important than timing. We knew that already. Larry specifically made a point of reiterating these messages and asking for our help in disseminating the information – it really bothers him that the myths are still floating around out there, and it bothers me, too. This misinformation can cause students to receive lower scores than they might have otherwise. The whole point of my job as a teacher is to help people get better scores – so I definitely don’t want to see anyone fall short of a goal because he believed a myth that we could have dispelled.
Also, I know you’ve heard this before, but it bears repeating:
“There is a severe penalty for not completing the GMAT test.”
– Larry Rudner

For those who may not have seen the data before, Larry again showed us real data showing how a 70th percentile test taker would drop if she left the last five questions blank. Assuming that she was at the 70th percentile when she ran out of time, that student would end up with a 55th percentile score – a 15-percentile-point drop! (Note: the magnitude of the drop can change depending upon the scoring level. As a general rule, the higher the score, the more of a drop if you leave questions blank or have a string of wrong answers at the end.)
Sentence Correction is more and more about meaning rather than grammarWe’ve already been speculating about this and other Sentence Correction changes on the forums, and Larry confirmed this one. GMAC has asked ACT (the people who write the actual test questions for GMAC) to emphasize meaning more on SC questions. There are an increasing number of questions in which two or more answer choices are grammatically correct and the key distinction rests upon maintaining the meaning from the question stem. If you’re concentrating solely on the grammar and haven’t learned how to incorporate meaning into your assessment, you’re going to find the real GMAT harder.
If you’d like to see some examples of what I’m talking about, crack open your Official Guide Verbal Supplement 2nd Edition and take a look at question 37. Answer choices B and E are both grammatically correct, but only one maintains the original meaning of the question stem. Which one? (I think this is a great study question for multiple reasons, actually – more on that in a minute.)
While there are several superficial differences between the two answers, the major difference is in the placement of the phrase “last year.” Last year is a modifier that tells us when a specific action or event occurred. What happened last year?
According to the original sentence, the earthquake occurred last year. Do both answer choices B and E maintain that meaning? Nope. Only B does. E says that the buildings had been constructed last year. How do we know that?
“<Last year> some <of the buildings> <that were destroyed or heavily damaged> <in the earthquake> had been constructed…”
The stuff in brackets is all modifiers. The word “some” is the subject and the verb is “had been constructed.” “Of the buildings” modifies “some.” “that were destroyed…” modifies “buildings” and “in the earthquake” modifies “destroyed or damaged.” In other words, the subject “some” has a bunch of modifiers following it, but the modifier “last year” precedes the subject. “Last year” has to modify some kind of an action or event. The subject “some” isn’t an event or action, so “last year” can’t modify that. The next core part of the sentence is “had been constructed,” which is an action, so “last year” modifies that action. Note that, in the original sentence, the modifier “last year” appears as part of the prepositional phrase “in the earthquake last year” – that is, in the original sentence, “last year” is part of the nested modifiers for the subject, while in answer E, “last year” has been sort of pulled “up” to the level of the core sentence. And, voila, the meaning has been changed.
The other reason I really love this problem: it also illustrates a case of when we should change the original meaning of the sentence. Most of the time, we’re going to be maintaining the original meaning… but sometimes there’s something illogical about that meaning. In question 37, the problem says that some buildings “were destroyed and heavily damaged” but that doesn’t actually make sense! A building is either destroyed or heavily damaged, but it can’t be both simultaneously because these are two different states on the same continuum. The correct answer, B, switches that “and” to the more logical “or.” (Note that answers B and E both make this switch – they’re both completely grammatically and logically correct, so this one really does come down to the ability to maintain the original meaning of the sentence.)
Stop stressing about idiomsWhen we asked Larry about the relative importance of idioms on the SC section, he said basically zero! They’ve asked ACT to phase idioms out completely and, ideally, there already aren’t any more questions that hinge on knowledge of idioms. (Though he doesn’t guarantee that, yet – there may still be some.) Of course, there are still many idiom-based SCs in the Official Guides and GMATPrep – but, according to GMAC, that aspect of the questions is obsolete, so that’s really not where we should be spending our valuable study time.
That’s really good news, and I applaud GMAC for making this change. The only good reason to test idioms is when you are specifically trying to test someone’s advanced English-language skills – for a translation or editing job, for example. If you use the wrong preposition with some verb, people are still going to understand what you’re saying – and business schools care about your ability to communicate and make yourself understood, not whether you have 100% perfect grammar.
The one thing that I will mention that might still be valuable for testers, particularly non-native speakers: idioms that can interfere with your understanding of the broader message if you don’t know the idiom’smeaning. This will most often hurt you on Reading Comprehension, actually. I’ll give you an example of what I do, and don’t, mean.
Idioms that can interfere with meaning: For all her studying, she still failed the test.
Idioms that don’t interfere with meaning: More time spent studying isassociated with a higher GMAT score.
In the first sentence, the construction “for all <some action>” really means “despite.” Despite the fact that she studied a lot, she still failed the test. If you don’t know what that construction means, you might get the wrong message about the sentence. In the second sentence, the preposition “with” goes with the past participle “associated” because… well, just because that’s how the language works. You’ll still understand the sentence even if someone happens to use the wrong preposition there.
More To ComeWe’re still parsing through a lot of the data that we received at the Summit; as we have more for you, we will definitely share! And, as mentioned at the beginning of the article, we’ll have another article soon with details about the Next Generation GMAT.

反正对于没做完情况的大概意思就是说  比如你的VERBAL整体正确率在70%。。 然后没做完 会扣去15%的分。。最后分数就是55%。。

我一战的时候 和我朋友 Q分数一样。。 V的我比他高2分。。但是我没做完 他做完了。。我俩分最后悲剧的一样

你的V比他高2分?最后的分不是根据Q和V汇总得来的吗?怎么还一样?
