Mck2023One should use the Official Prep materials
Judiciously* (think of them as a gem).
IMO,
1. Never reset any exam, be it official or any other ,
as it might give you inflated score*. (which actually may make you feel happy at that particular moment), but which will not be the actual gauge of your potential to take GMAT.
* - There are only so many questions in a question pool, as many that cant be reset/shuffled. You are bound to get "attempted questions", once you have reviewed them, you will definitely get them correct. Hence, Inflated scores.
Judiciously*I committed the mistake of exhausting all the Official GMAT CATs + Prep Materials, just to be ensured that I have all the
Basic Skills+Concept knowledge+Test Taking Strategies (and i performed well in all of them). But in the ENDGAME I doomed.
Therefore, in my opinion, one should never reset any exam (even if it is allowed).
