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.

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).

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!
