Many, many questions are the same! Indeed, the '17 ed. states that it contains "130 never-before-seen questions." Therefore, 770 questions are probably repeats from previous editions. The questions are just re-numbered & shuffled. Sadly, the 2018 ed. = the 2017 ed. =( The diagnostic exams on p. 18 are exactly same on the 3 books. Example, the "Greenrock" question is the same in all 3 books. If you log on to MPrep, you can get free access to their Navigator function. Here, you can time yourself while sitting for some '17 ed. OG questions. The two older books are from thrift stores, $4 & $10 respectively. Sadly, the 2018 ed. cost $52, along with its 2 companion books. =( ^3 Take away: If you are wondering what the GMAT questions are like, just buy the 2017 ed. for cheap and log on to some free 5- or 7-day trial memberships. Save some coin! You are welcome. Players...I bid you Peace.
