General GMAT Questions and Strategies | Re: MGMAT Foundations of Math, Verbal & Advanced Quant-6th vs 5th Edition

Has anybody got a chance to review the 6th Edition of MGMAT Foundations of Math, Verbal and Advanced Quant and compare them with the 5th edition?

I can get the 5th edition of MGMAT Foundations of Math & Verbal from a friend for free, but I am not sure if the 6th edition would be more valuable. Also that I will get access to online resources by purchasing the 6th edition, but not sure if that would really be valuable. I recently purchased the 6th edition of the MGMAT Complete Strategy Guide
