Hi Moroni,

The OG13 is still a worthwhile book of practice questions (the GMAT2015 is the exact same book, but with some online companion tools; the GMAT2016 replaced about 25% of the content and also includes those same online tools). So you would be fine including any of those books among your various study resources.

GMAT assassins aren't born, they're made,

Hi Moroni,

Our tests can be accessed from anywhere, so yes, that's still a valid offer. :)

When you buy our book, you'll also have access to lists of recommended quiz questions in the OG. This is keyed to the latest edition of the OG, so it would help a bit to have that book, but as Rich mentioned, 75% of the material is the same.
