Are the 4 free MGMAT challenge sets found on this forum same as the 6 MGMAT CAT tests that come with purchasing their book(s)?
No, they are not.
The 4 free sets are the "Hard Collection" from MGMAT (their challenge of the week series).
Hope this helps.
Thank you!! Another silly one......I assume the OG diagnostic isn't repeated by the GMAT Prep CAT questions?
