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).

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!

请买到的同学尽快制作PDF版本上传吧，

尤其是先把SC,CR弄个PDF版分享，O(∩_∩)O~

国内买不到，从Amazon买，书倒不贵，主要是UPS费用太贵。。。

首先感谢楼主提供信息

另外，PDF最好不要上传上来。CD招人，万一涉及版权就不好！OG11我听管理员说就是怕版权所以不让下载了。！要发发到太傻之类的去吧，然后在这给个链接。或者是发到自己的网络硬盘等等。

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).

 

 

逻辑

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.
