So I have already gone through the OG11 and am saving the OG Quant for later on, so I am currently working through two of the
MGMAT guides. I like the books a lot, as they provide clear and easy-to-understand strategies. But I am finding them lacking in practice exercises. I would like to get more practice by topic, especially with tougher questions. I read about Total GMAT Math and the practice sets put out by Jeff Sackmann and am wondering if I should switch over or purchase it as a supplement. Does Total GMAT Math do a good job of explaining probabilities and permutations and such? Or should I get the
MGMAT Word Translations book? Is Sackmann's stuff the best practice material out there, or is there a better option (besides the OGs)? Or should I just stick with
MGMAT for material (since I'm already a good way through both books) and just purchase sets from Hackmann? Will I miss out if I don't get Total GMAT Math?
