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.

Anytime, Jerembo! Unfortunately, I won't be able to answer your question coz I haven't looked at the new questions yet. Just compiled the stats from Margarette's original post. Maybe she could answer your question.

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!


I believe there's an online component accompanying OG 13th that covers IR section.

Dear Jerembo,

I'm actually the one who compiled these question for the Excel document that my esteemed colleague Margarette posted.

I haven't done a formal study of each and every new question in the OG 13, but here's what I can say from my overall sense of the questions. Maybe about 1/3 of them at most, while new in superficial presentation, are clearly a reworking of either a dropped question in the OG12 or an earlier question --- in this case there has been just a slight change in emphasis. The others, though, are quite new, both in terms of content and in terms of format; that's the vast majority of the new questions. As a token example --- OG 13 PS #199 --- there is NOTHING like that in any previous released question that I have seen. That is a completely and unapologetically NEW question.

I discussed, very briefly, some of the trends I noticed in the new math questions in this post:
http://magoosh.com/gmat/2012/sneak-peek ... tion-math/

Now, does knowing all this help you at all as a test-taker? I don't know. If you are just coming to the GMAT now, and you have bought the OG13 and are studying with current materials, then how the GMAT was in all its previous iterations really doesn't matter ---- in fact, it's entirely irrelevant to your current GMAT preparation process. If you bought an OG12 when you started studying, and now have an OG 13, and want to know the changes, it would be convenient to see which questions are new --- that's precisely why we posted this spreadsheet. If you have been following the GMAT assiduously for years as it has developed and changed as a test, you might be more interested in the logic behind these changes and the larger trends over time, but I think that situation applies far more to those of us who work in the test prep business, and relatively rarely to an individual test-taker out there. From what I have seen, most people go from the beginning of studying to their final sitting for the exam in well under a year: I believe few people outside of the test prep business have paid consistent attention to the GMAT over the course of several years. That's really a perspective beyond what the average GMAT test taker has or needs.

Does all this make sense?

Mike :-)

Yes, what kblade said is perfectly correct. Each new copy of an OG 13 comes with a code that will give you access to the online complement of the OG. This site has 50 IR questions in full test format (separately viewable cards, sortable tables, etc. etc.)

Of those 50 questions,
#1-18 are MSR questions
#19-24 are TA questions
#25-34 are GI questions
#35-50 are 2PA questions

The format of the questions (prompt length, number of answer choices, etc.) and their difficulty level are apparently representative of what test takers will see on the IR section when they sit for the real GMAT. When the IR questions were first introduced, GMAC gave some free examples on their site, but since then their ideas for the IR have been evolving. Apparently, the format and scope of these 50 questions represent the endpoint of that evolution process: ostensibly, they represent how the IR questions will appear on the test. In early to mid August, I am going to publish an article on the Magoosh blog giving details about exactly what these 50 questions tell us about the IR section and each of its four question types.

If anyone reading this has any questions, please let me know.

Mike :-)

Hello,

I have added a few formulas to the original xls so that if you choose the conversion type(OG12-13 or OG 13-12), section (verbal/quant)and subsection (DS/PS/CR/SC/RC)and input the question number, you will get the corresponding question number in OG 12 or 13.

I did this so that I can quickly get the question number rather than navigating through the tables. This may be little value for others, but just my small contribution.

All credit goes to the Magoosh.

If the reuse of content is against the board rules then please accept my apologies and delete the file.

Thanks

Hi, Anilisanil

We certainly don't mind! Thank you very much for doing this, I'd definitely encourage students to use this to save themselves some time! :)

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)



Fine gist made for the 'fine tuning'.. Nice work...:)

Breakdown of Common GMAT Official Guide Practice Questions: 13th Edition vs. 12th Edition


Mike McGarry, GMAT expert at Magoosh, has compiled several tables comparing old questions in the OG12 to new questions in the OG 13. You can see which questions in OG 12 were dropped and which questions in OG 13 are new.

You'll find this helpful if:


  1. You own one of the two editions, and want to know exactly how much unique material you would gain by buying the other.
  2. You own both editions and want to identify the repeat questions.

These spreadsheets include tables that specify which old questions got dropped, replaced with new ones, or kept the same. They're organized by section/question type, and there are two sheets: OG 13 --> OG 12 and OG 12 --> OG 13, so that you can compare in whichever direction is more convenient for you.


The Diagnostic Tests
The Diagnostic Test is 100% identical in both editions. Not only is every question the same: even the layout and the page numbers are identical! Not one jot has been altered.

Quantitative: Problem Solving
In this section, 45 questions in OG 12 have been replaced with new questions in OG 13.

Quantitative: Data Sufficiency
In this section, 36 questions in OG 12 have been replaced with new questions in OG 13.

Verbal: Reading Comprehension
In this section, 26 questions in OG 12 have been replaced with new questions in OG 13.

Verbal: Critical Reasoning
In this section, 25 questions in OG 12 have been replaced with new questions in OG 13.

Verbal: Sentence Correction
In this section, 25 questions in OG 12 have been replaced with new questions in OG 13.

Takeaways
Let us know whether you find this type of breakdown helpful, and any questions you might have about any of the information above! Also, any suggestions or requests for other similar GMAT material-related breakdowns, are also welcome :).


Hi Margarette,
This is just awesome....!!! Kudos.... :)

thanks for the file (Magoosh_GMAT_Official_Guide_12th_vs_13th_Edition.xlsx).

I found that an entry for DS requires a correction:
DS(OG13)-173 currently maps to DS(OG12)-119, but it should be DS(OG12)-172

Dear Samg,

I apologize for the delay. I believe we corrected the remaining errors, and a new improved (error-free?) version is now posted in the lead article of this thread.

Let me know if you have any questions.
