I am wondering if anyone knows if the 800 question expansion pack on the official GMAC iPad app corresponds to the questions in the GMAT official guide to both Verbal and Quantitative Reviews? (The two supplemental books that are mentioned in the 60 day study guide) If so, I was going to just purchase that pack and not the 2 books to save space. But, if they don't correspond to the problem numbers that are given on a daily basis in the emails then it wouldn't be a good purchase. Thanks so much!
