Hi! I purchased the MGMAT series books and I love them and the GMAT navigator! I also purchased the 2017 edition of the OG, Quant, and Verbal, but as I'm practicing FDP sets there seems to be a limited number of MGMAT created explanations available for the 2017 guides. Is it safe to assume that if I buy an earlier version that there will be many more MGMAT explanations available in the Navigator? The OG explanations in the back of their book are terrible in comparison to your rationales. Thanks in advance for your help!
