OG 10 vs OG 11

Expert replies

Hi Folks,
I am in this quandry: I have both OG 10 and OG 11 which I am yet to start. The questions that I have are
1. Is OG 10 still relevent coz OG 11 is around?
2. OG 10 says it has around 1500 Q and OG 11 says it has around 800 Questions. Is there any overlap of questions between OG 10 and OG 11 (i mean r there many questions are a VERBATIM repeat)

3. What are your suggestions on how to use these two OGs for best benefit?

thanks a lot

I have heard on this forum that there are repeat questions from OG10 in OG11.

Since OG11 is the recent one, it would be more representative of the test. You could first complete OG11 and consider OG10 for additional practice if time permits.

There is 75% overlap (the exact same questions) between OG10 and the current generation of books (OG11, Quant supplement, and Verbal supplement, which together equal about 1400 questions).

So if you've already got them, it doesn't really matter too much - but might as well do OG11 as presumably some of the questions that were dropped were dropped b/c the testwriters thought they weren't as good or were no longer as representative or something like that.
