A little question for you
For qualifications for the French Baccalaureat level there is a drop-down list to select the result. We can select in the list grades from 1 to 7.
The problem is that in France we get grades between 0 and 20... Could someone indicate me if the equivalence for a 17/20 (for example) would be a 1 or a 7 ?
Thank you!
