I think in OG11 there are fewer questions to practice. It has around 900 questions in total (quant + verb + diag).

Though I haven't seen OG10, but have only seen cover on net, which says total around 1400+ questions. Is this true ?

Get a decent book - depending on your needs you can get a lot of great books. What you are doing right now is setting yourself up for 640 and then needing retake but by that time you would have "wasted" all of the OG questions, GMATPrep, and other resources. Get good books - they are worth it - usually the more specialized, the better.

GMAT Guidebooks (All-in-one): top-gmat-prep-books-guides-reviews-comments-77703.html

Specialized:
Math GMAT Books
Verbal GMAT Books


OG 10 is considered by many the best of OG's.
The only weakness of OG 10 is that it has many questions overlap with PowerPrep - the predecessor of GMATPrep (download PowerPrep)


P.S. I saw that template and indeed - it is a great idea. Can you kindly post the source so that I can give proper credit?

Thanks!

BB: Hmmm....okies. Then its Kaplan Maths workbook vs. MGMAT guides. Let me see which is available here. Thanks for your inputs :)

Bigoyal: You are right. OG 10 has a total of 1400+ questions with the following breakup:
PS - 441 questions
DS - 274 questions
CR - 205 questions
RC - 285 questions
SC - 268 questions

Also, the overlap with OG 11 is minimal. However, as BB rightly pointed out, there is a higher degree of overlap with powerprep. But, since we use GMATprep instead of powerprep now, I don't think it really matters. And that book feels really great and is a great inspiration to just start studying (I have a hard copy :))

BB: The name of the template creator is topher and the template is posted at please-evaluate-my-study-schedule-79588.html. I should have done it before but was just being lazy :P.

Is OG 10 useful to prep from? From what I understand, OG is the bible. Therefore, wouldn't practicing from OG, rather than from other books (Kaplan, PR etc.), make more sense? I know the questions are retired and old, but they do have the same difficulty level and test on the same concepts, right :?:
You have the point overhere - OG 10 is better than any other review book, including Princeton Review, not even to mention Kaplan. If you already have it, work with it. If you don't, I'm not sure it's wise to buy it now. Instead, you should spend your money on some guides like MGMAT.

In addition, because I am pretty weak in quant (DS is my nemesis :evil:), I am going to work through Quant review Ed 11. Does this sound enough?
OG is definitely not enough, especially if you have some issues with math. OG Quant Review (purple book) will not bring you nothing but additional questions, which is good, but you need some guide with methodological approach because you have to learn concepts, not just to practice with sample questions. In that sense, I can recommend you MGMAT for some medium-to-advance concepts and some book like Sackmann's Math Bible for some basic-to-medium concepts.

In that case I think it would be worth giving a try to OG10 instead of OG12.

Btw, any idea why there was such a significant drop in the number of questions from OG10 to OG11 ?

In my opinion the overlap is not minimal. It is nowhere less than 30-40%.
I know that the number of problems you get to solve in OG 10 is more than OG11 , I will not suggest OG10 to someone who wants to be away from OG. (It is not suggested to start the prep with OG.)
