Almost always all the candidates and the companies that prepare to the GMAT focus on the importance of the official guide.
Is that because the OG questions are all real retirees GMAT questions or because - in addition to the latter - the real GMAT exam asks some questions that has been taken from the OG? Moreover, do the GMAT exam questions resemble to those of the OG 13
in a way or another?
And what about the official guides verbal review and the quant review? Is it a good idea to do the questions in both at the same time we do resolve those of the OG 13th
edition or do we take them once we are done with the OG 13th
Many thanks for your help on that !
Yes, the OG is critical for realistic questions. GMAC folks are constantly working on new questions and testing them as "experimental questions" on real test takers. But OG and GMATPrep are the most realistic type questions you can study from -- so you should treat these as your primary source for practice. Use the verbal and quant review books as supplemental resources AFTER you've gone through OG. Then, of course, go back to OG and test yourself yet again.
Make sure you track your OG responses online here - and watch video explanations: http://www.gmatpill.com/official-guide-gmat/
