I'm a bit of a completest so despite already having purchased OG 12th edition and the latest OG Quant and Verbal Reviews, I'm wondering whether it is also worth buying OG 11th edition?

Looking through that excellent Manhattan link posted earlier on in this thread, it appears that the OG 12th edition is missing a large number of questions that actually appeared in OG11:

*Reading Comprehension: missing 45Qs from OG 11th edition.
*Sentence Correction: missing 55Qs from OG 11th edition.
*Critical Reasoning: missing 50Qs from OG 11th edition.
*Problem Solving: missing 75Qs from OG 11th edition.
*Data Sufficiency: missing 75Qs from OG 11th edition.

So by also purchasing OG11 I will gain an extra 300 practice questions. Surely this is worth it especially considering the low price for old editions?

Any views?

I think the more official questions you solve the better. By the way, I would also consider OG Verbal 2 and/or OG Quant 2 books.

Thanks Walker, I'll probably pick up OG 11th edition as well then. When I said:

I did mean that I've already got OG Verbal 2nd Ed. and OG Quant 2nd Ed. :)

Are the questions contained in the OG Verbal/Quant 2nd Ed. books definitely not duplicates that can also be found in OG 11th ed?

Also, do you know if there is a list showing the questions that are only in OG 11th and NOT in OG 12th?

At this Manhattan link: https://www.manhattangmat.com/official-guide-12.cfm, there is a PDF for each subject section that highlights the new questions that have been added to OG 12th. But also contained in each of these PDFs, e.g. take the Problem Solving one: https://www.manhattangmat.com/pdf/Proble ... fa12ed.pdf, on the 3rd page there is a list entitled "Sequential Problem Correspondence between 11th and 12th Edition"; where there is an n/a in the right hand column for OG 12th, can I deduce from this that the question number in the left hand column is only printed in the OG 11th ed?

Thanks for the help.

No problem Walker!

So does anyone have any info regarding:

as I really wouldn't want to purchase OG 11th ed and go through the book manually finding which questions don't appear in OG 12, that would take too long.

i am planning to go through the questions in OG10, but is it true that OG10 questions appear in the 2 Free GMATPREP tests. If that is the case, i would start attempting OG10 questions only after attempting the 2 GMATPrep tests.

Hi Ghiwa,

The Kaplan books and the OG books fill completely different niches. The OG is a way to get the most realistic problems possible. At Kaplan, we do everything we can to make our problems as close to the test as we can--but the OG problems are straight from the test, as good as it gets! However, the OG is mostly a resource for problems, and nothing more. What strategies it offers are few and far between. Kaplan GMAT Premier includes strategies, patterns, and content in much more detail that the OG will teach you.

I hope this clears up the difference--pick the one that's best for you!
