Thanks lsuguy7 and nink for your replies !
Well that is the point, lsuguy7: I don't know if
- a higher GMAT score really increases chances of admission,
- or if it does not do any difference as long as you have a score above the unofficial minimal one ...
To answer to nink, my background is the following:
1- top-ranked "grande école" in France (selection by my university of the scientific undergraduates top 0,5%)
2- and then elite governmental leadership programs (admission rate: 2%) in telecommunications / industry sector.
So as it is a "solid" background and I am sure INSEAD knows it (they are partially French !), I am wondering if they would not expect from me to have a "solid" score reflecting this background... i.e. no less than 750 ...
I am starting to regret having spent only 1 week to prepare the GMAT ...
