Breakdown of Official Guide 13th Edition vs. 12th Edition

@mathurmudit1003
IR is not counted in the main score, which is out of 800. IR will be counted on the scale of 8, similar to argument( scale of 6).

im doing OG12 first and then will switch to OG 13, this is EXACTLY what i need to avoid repetition and practice targeted new questions. Thanks, your IR guide was super helpful too.

Nice document...

Do any one has a question break up for critical reasoning in the form of Strengthening, undermining, paradox etc catagorised...for eg:

Strengthening---Q1,Q3,Q100

ETC

The breakdown is certainly helpful and segregates what is different in OG13. Appreciate your efforts and valuable time. Thanks

Really great job! GMAT Club is te best resource ever

I'm using 11th edition, but the breakdown is useful since it identifies the passage topics in the reading comp..but that's about it. =P

This would be of great help!! Thanks a ton

hey guys, I have just started with OG 13th after OG 11th. Do I need the OG12th??

Also, in OG13th there aren't any questions on IR? Can you suggest some ways to practice questions of IR section?

Thanks!

Thank you for posting these tables. I haven't looked at the verbal side yet, but on the quantitative side, there seems to be errors in the Data Sufficiency tables. For instance, the tables claim that #3 in OG13 DS corresponds to #2 in OG12 when it actually corresponds to #3 in OG12. There are other errors: the attachment indicates that #1, 2, and 4 in OG13 DS are new questions when in fact they correspond to #1, 2 and 47 in OG12 DS etc... The problem solving tables are great though.


Just a heads up for people using this as a reference. Does anyone know of another resource that maps questions accurately?

Thank you for that resource. It is great for finding out which problems are new, but unless I missed something, it does not include a reference that ties repeated OG12 problems to their corresponding number in OG13.

Hi, Patrick

We've just fixed the errors and I updated the upload in the original post with the new version. Let us know if you find any other discrepancies, and I'm sorry for the confusion!

Best,
Margarette

Thanks for the update Margaret. The DS section is much more accurate now. It will take a while for me to check all the questions.

In the PS table, there is one error. The document claims that #20 in OG13 is new, but it is the same question as #203 in OG12.

The DS table (in the first tab) incorrectly indicates that #170 in the OG13 has been dropped. The correct link is made in the 2nd tab.

-Patrick

It's been fixed, thank you!


DS #170 in OG 13 should be listed as "new", not "dropped", so that's been fixed, but it should not be linked to DS #167 in OG 12-- although the questions are based on similar concepts, they're not identical, which has now been accounted for as well.

Thanks for your help!

Thanks Margaret,

I can't tell the difference between DS #170 in OG13 and DS #167 in OG12 so I'm probably missing something.

Anyway your document has been very helpful. I'm glad you shared it.

Super helpful post! Thanks a ton!

Quick piece of data for anyone who has the 12th edition and is unsure whether to buy the 13th. Here is the %age of new questions in the 13th edition (Overall 20% questions are new):

Quantitative: Problem Solving - 20% (45/230)
Quantitative: Data Sufficiency - 21% (36/174)
Verbal: Reading Comprehension - 19% (26/139)
Verbal: Critical Reasoning - 20% (25/124)
Verbal: Sentence Correction - 18% (25/140)

Great info - thanks wannabegmathero! Do these additional questions derive from old tests ("retired questions") or are they just manipulations of prior real problems - is there a difference? Thanks.
