Hi all,
TLDR: What purchases of OFFICIAL materials MAXIMIZE the number of unique official questions?
Overall Im a bit confused on the difference between various OFFICIAL question sources. From online, it seems like many of them overlap quite a bit. Can someone clarify the differences/overlaps in these official question sources?
1) questions available on the Wiley portal (app.efficientlearning.com)
2) questions available on the gmatofficialprep.mba.com portal
2a) I have completed a few official practice tests. Is it correct to say that the official mock tests' questions are DIFFERENT than the others that just show up in the middle of this portal? Since they are all accessible, from one point, I cannot tell if completing questions here will take out of the purchased practice tests.
3) Official questions in each separate practice test -- do they overlap with any other official resource?
4) Official questions in each "review book" (ex. Official Verbal Review Book that has a lot of questions, etc.)
Which of these overlap vs dont? How can I get the max number of unique questions? I am a bit lost since forums show that there is overlap and there seem to be multiple names for each test (ex. Gmat prep vs OG etc?)
Please help clarify!
