OG 12th 重要信息：OG12 Vs OG11 详细区别 （带题号）

VERBAL

In short, the changes are not minimal, but they are not radical, either. Each Verbal chapter contains 30-45% new practice problems, with the most new problems available in Sentence Correction. There are also some subtle, but noticeable, differences in emphasis. For instance, in Reading Comprehension, the rare Roman Numeral question type has been eliminated in the new OG. (Check out RC sample problem 113 in the 11th ed. for an example of this question type.) We don’t know for sure if this means that the GMAT will no longer show Roman Numeral questions, but it does suggest that they may appear less frequently.

More importantly, the Critical Reasoning section is different in two notable ways. First, gone are all Critical Reasoning practice questions in which two or three questions follow a single prompt (check out CR problems 60-61 in 11th ed. for an example of these paired questions). These "prompt siblings" have been replaced with a question sub-type in which an argument is presented, two statements are put in boldface, and the question asks the test-taker to identify the roles of the statements in bold. This is a positive change; these questions have appeared in the official GMATPrep tests, without any analogue in the old OG, for some time. Hopefully, the new CR section will make for more authentic practice.

We welcome any further comment on these changes to GMAT format, content or anything else. Below, find our numerical breakdown of new questions (along with a list of every new Verbal practice problem in the 12th Edition of the OG).

Math

TOTAL (MATH):

11th Edition: 404 questions
12th Edition: 404 questions

New questions in 12th Edition: 146 (36%)
Repeated questions in 12th Edition: 258 (64%)

PROBLEM SOLVING:

11th Edition: 249 questions
12th Edition: 230 questions

New questions in 12th Edition: 52 (23%)
Repeated questions in 12th Edition: 178 (77%)
Questions deleted from 11th Edition: 71 (29%)

DATA SUFFICIENCY:

11th Edition: 155 questions
12th Edition: 174 questions!

New questions in 12th Edition: 94 (54%)
Repeated questions in 12th Edition: 80 (46%)
Questions deleted from 11th Edition: 75 (48%)

As you can see, the total number of questions has not changed, but there are now 19 fewer Problem Solving questions and 19 more Data Sufficiency questions. We think this is great, since, in our experience, most students have more trouble with the DS section.

There are also many more new DS questions (94) than there are PS questions (52). Here is a complete list of the new questions in each section (question numbers in the 12th Edition).

Stay tuned for our analysis of the Verbal Section, coming soon. Let us know if you have specific questions we can look into!

3大板块 定性 分析

 

语法：

1. Like the other problem types, Sentence Correction has not changed greatly from the 11th to the 12th editions. Do not forget this point as you study the nuances of new problems.
2. The GMAT continues to look for ways to penalize unwarranted shortcuts. Certain awkward expressions are often but not always wrong, and the GMAT has included problems that force you to choose these expressions, such as being (in #101) or the fact that (in #83). Remember that the right answer is not necessarily graceful, but it must be grammatically correct.
3. Explanations for repeated problems have generally remained the same, but occasional changes have been made that may indicate a slight refinement in the GMAT's thinking on particular issues. For instance, the explanation for problem #7 in the 11th edition condemns the use of which in restrictive clauses and instead insists on the use of that. This problem has been preserved verbatim as #10 in the 12th edition, but now the explanation says that the rule against which in restrictive clauses is "controversial." As it turns out, none of the wrong answers in the problem fail solely on this basis. Nevertheless, with its new explanation, the GMAT has signaled that it will almost certainly never write wrong answer choices that can only be eliminated with the which rule.
4. A few idioms have been added or returned to the working lexicon of GMAT Sentence Correction. Some of these, such as not just X but also Y, are variations of well-known idioms. Of course, you must be extremely careful not to draw too many analogies with idioms, which by definition resist classification. For instance, one new problem (#140) uses the word dated, which must go with at, not to be, when you express an age: This fossil has been dated AT 10,000 years old, not TO BE 10,000 years old. In contrast, a seemingly similar word, estimated, must be used in precisely the opposite way with ages (This fossil has been estimated TO BE 10,000 years old, not AT 10,000 years old), as is tested by problem #27 (#21 in the 11th edition).

1. The most interesting shift is the growth of the minor types, particularly Analyze the Argument Structure, as mentioned above. Analyze the Structure problems were under-represented in the 11th edition (in fact, only one boldface statement problem exists – and it’s in the Verbal Supplement, not the 11th edition itself). This problem type is generally difficult, since the arguments are generally long and complex, and the answer choices are often worded in confusing ways. Students should be sure to practice problems of this type. Also, Evaluate the Conclusion deserves additional attention, although the new problems are concentrated in the lower (easier) numbers.
2. An interesting new structure appeared in one Explain the Event problem (#22). In this problem, a plan is outlined, together with the result (the failure of the plan). Finally, further information is provided. This further information allows you to rule out some possible explanations for the failure of the plan.
3. Several new problems contain rather long chains of cause and effect (e.g., #49, 62, 112). Students will continue to need effective techniques for keeping track of complex arguments.

1.     Reading Comprehension has not really changed. The content and style of the new passages and questions is very similar to the content and style of removed passages and questions.

2.     As was mentioned earlier, Roman-numeral questions have been deleted. Since the associated passages were retained, together with all the other problems, this deletion is a fairly strong signal that the GMAT may be moving away from this sort of question. However, there were only 2 such questions in the 11th edition; this type of problem was never very important.

OG 12版相比11版的变化

 

Only 1/3 of the questions are new. Out of 907 problems, 607 are repeats. The best way to look at the 12th Edition is as a source of 300 great new practice problems.

 

Much of the book is completely unchanged:

• Most explanations for repeated problems have been untouched, though some have been improved.
• The Diagnostic Exam, Math Review, Test-Taking Strategies and Directions are unchanged.
• Excluding the Diagnostic Exam, sample questions are organized by difficulty, according to the GMAC – just as they are in the 11th edition.

The removed and added problems constitute a slight shift in the relative emphasis of certain topics, but the underlying content is essentially the same as that covered in the 11th Edition.

 

In fact, of the 300 new problems, many of the new Quant problems can be found in GMATPrep? or GMATFocus? (both GMAC products).

 

It is important to note that you should not over-interpret the changes from the 11th Edition to the 12th Edition! Some variation is to be expected. Nothing in these changes suggests a notable shift in how students should prepare for the exam.

DS题：

The 12th Edition has 19 more Data Sufficiency problems than the 11th Edition. Moreover, 47% of the Data Sufficiency problems in the 12th Edition are new. For other question formats, turnover is in the 22%-36% range.

In addition, the 12th edition has 19 fewer Problem Solving questions than the 11th Edition. These shifts may suggest an increase in the relative importance of Data Sufficiency, but this is not certain.

OG 12th Edition刚刚拿到OG12版，感觉变化不大，前105 页几乎一样。

比11版多了8页，大概是因为一些题（和11版重复的题，主要是VERBAL部分）的解释多了一两行

目前只对了RC部分，一共24篇阅读，16篇从11版来，还有3篇从GWD来，估计其它5篇也能从GWD找到（小弟GWD还没全部做完），如果发现会继续UPDATE。所以GWD真是好东东。

还没时间看CR和SC，但估计重复的比例也差不多， 16/24=67%

so far, I haven't seen any "Insights into the GMAT exam that debunk test-taking myths" and don't think will find any.

先把阅读部分的题目对号入座下，其它部分会继续UPDATE（惭愧，SC只做了一遍，这大概是为什么，大全做了两遍，还是有30%的错误率 CRYING~~~）

RC:


OG12(OG11); 4-8(8-12); 9-11(13-15); 12-17(21-26); 26-30(27-31); 42-46(43-47); 47-49(48-50); 50-56(51-57); 57-63(TN-24-8, 25-28); 64-69(58-63); 70-75(70-75); 82-90(76-84); 91-96(85-90); 97-102(97-102); 103-107(TN-24-6, 4-6); 108-114(103-110); 115-119(111-116); 120-127(TN-24-6, 25-28); 128-133(117-122); 134-139(123-128)

小弟4/13/09一战

目前水平实在有限，而且在职，有些力不从心。希望周末前可以UPDATE完。也请其他兄弟姐妹，如果有12版的，一起UPDATE


03/18/09 2000

SC: 目前看到和11版一样的只有52到题，一共140道， 有些题貌似在GWD里, 解释部分，没有大的出入，有个别题，多两至三行的解释。

如果有其他XDJM看到，请继续UPDATE。我这两天会把SC和CR做一遍，有新的发现，会继续UPDATE

OG12 (OG11)

2(1); 5(3); 10(7); 17(14); 24(19); 25(20); 27(21); 32(26); 42(39); 44(40); 45(42); 47(43); 49(44); 50(45); 52(46); 55(49); 57(50); 59(51); 60(52); 62(54); 64(55); 65(56); 74(62); 79(67); 82(73); 85(75); 87(81); 89(85); 90(86); 92(87); 94(88); 95(90); 97(95); 102(98); 104(101); 105(102); 107(105); 109(106); 110(109); 112(111); 114(113); 115(114); 117(115); 120(121); 122(126); 127(129); 129(131); 130(132); 134(134); 135(135); 137(136); 139(137)


03/18/09 2118

SC：刚才做了12版SC前50道题，发现11版黄皮上没有的，紫皮上一道也没有。

但99%的题都见过，个人认为是大全或者PREP320 里的（大全，PREP320 我各做了两遍，GWD只做了9套，到目前）

就目前来讲，可以得出的初步结论是EST的出题思路大致没有变化。

4月份考试的XDJM包括我自己，也可以稍微放心点。

OG11上海

 

买到，新东方门前小摊上买的
三本80块，上海新东方门口。

盗版的，质量不怎么样。

有兄弟70块都买到了，俺不大会砍价

 

北京

北京海淀图书城有卖，120大洋

 

我在新东方旁边的二月红书店买的，只做了review的sc...觉得质量还不错。店主说是原版影印，没有错。130买的...应该还能坎坎价...

具体地址楼主搜一下，应该能查到。我就不贴了...免了做广告的嫌疑。


中关村北一条7号 (新东方总部西侧中关村二街向北50米) 010-62557599

 

 

广州购书中心5楼有得卖~~

忘了是哪一家店了，价钱是168，三本

 

我的OG在勤为径书店买的，在东山区新东方附近，这是电话020－8768 2269

几天前去香港，在PageOne和商务印书馆都有的卖，原版的，其中一本320HKD，另两本每本也要100+HKD，没买。今天刚问得深圳也有的卖，非正版，148RMB每套，准备下班去看看，在福田医院嘉汇新城，具体地址：

 

网上：amazon.com或者mba.com

 

今天终于买到了 OG11（武汉）今天下午在武汉新东方（武昌总部）门口与小贩商量购买OG11，一共三本，没有光碟，印刷很清楚，但是价格较高，开价130还不还价，愤怒了，于是找另一卖家，终以100元拿下

 

 

在北美买OG11的朋友一点建议。上个星期老公在AMAZON给我买了OG11（两本：verbal and review)一共40多美金，但是第一次在那买东西，给30多的打折，所以就只花了11刀，邮费不花钱。今天收到了，属绝对原版。很经济。建议没在亚马逊买东西的朋友在那买，比MBA便宜。

 

长沙

天马公寓那里有个专售新东方以及出国丛书的小店看看，就在转弯的左手边，还没有到移动缴费厅

另外别的地方就只能到新东方的两个校区附近问下罗，一个是在荣湾镇（岳簏山大门的斜对面），一个是在定王台（天桥下面新华书店对面），我估计新华书店里头可能没有B版的书买
