GMAT Strategy

I noticed that this just came out.

Great... more stuff to buy now.

Can anybody tell me if there is any overlap between this and OG 10-12?

And how much overlap if there is?

I already have the old OG Quant and Verbal Review 1st Edition (in my opinion not overly helpful - waste of money if you had OG 10 and OG 11)

Is this the same story this time? Same material covered in OG 12?

Anyone's input would be greatly appreciated. Because I'm not interested in lining ETS's pockets any more than I already have.

Thanks.

I'm surprised you found the first editions unhelpful. As far as I recall, there was no (or at least extremely little) overlap between them and OG 11. I haven't seen the second editions yet, but assuming that there is no overlap again (someone else will have to chime in regarding this), I would definitely buy them. Seeing more official questions - especially for verbal - is always a great help.

There was definitely overlap if you had done OG 10 and 11.
