Which OG?

[gkoszorus]

I recently purchased the 8 strategy guides and I was wondering which OG I should use for the quantitative books (OG Gmat Review 12th edition or Quantitative Review 2nd edition)? Or should I just purchase both of them?

hi -- welcome to the forum. you posted this question in the wrong folder.
this time i moved it to the correct folder for you, but please try to pay attention to where you post things from now on.

the PRIMARY book is og 12th edition. the problems in that book are newer, and so more accurately reflect the evolved priorities of the test.
the quantitative supplement still contains good problems, but those problems are older -- so they may bear somewhat less resemblance to what is currently on the exam. still, (a) it's still a good book and (b) the test doesn't evolve that quickly, so both books are of value.
