Analysis of OG Verbal Review (SC, RC, CR) 2016

You are welcome!
I hope you get your answer by Empower GMAT.

Thank you Rich and zmtalha.

I am specifically talking about the verbal review 2016 (4th ed) and quant review 2016 books (4th ed) . Not the OG 2016. What Rich has provided is only OG 2016, and not about the other 2 books of the set. Unless I am horribly mistaken and not able to compare it correctly.

Any feedback on this regard is greatly appreciated.

Thanks again

Hi herein,

Since the subject-specific OG Books are not used by nearly as many Test Takers as the larger OG book is, I'm not sure if anyone has done the same type of thorough 'break-down' of those books as we've done with the larger OG. The subject-specific books include 25% 'new' content (relative to the prior versions) - meaning that approximately 75 questions in each book have been 'replaced' with 'new' questions. If you're looking to practice with the most realistic questions, then those books are arguably some of the best sources. The relatively low cost of those books also makes them some of the most affordable materials for purchase.

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

My analysis is between VR 2nd edition and 4th edition indeed. I haven't done similar analysis for Quant review.
