I will not be taking the exam after June 5th, so i will avoid the IR portion which the OG 13 guide attempts to help you prepare for. Is the OG 13th guide worth purchasing then? I am specifically looking for new questions, because the OG 12 guide I have gone through twice already. I however, have never used the Verbal or Quant supplement, and I wonder if the OG 13 guide is just the OG 12 guide plus the 2 supplements. I've gone through Powerscore, OG guide, MGMAT 8 Guides, and I have not taken a practice test, but I scored a 640 on the real exam back in September. I'm wondering what other material I should be practicing with to help bump me to a 700.


any help appreciated.

About 80% of the OG13 questions are the same as those in the OG12.
So, if you're taking the test before the IR section is implemented, the OG12 will be good enough.

If you're looking for extra practice questions, this forum is all you need. There are 1000's of challenging questions here.

Cheers,
