Hello

Nift has relative grading system. It is basically depend upon the entire class and not the standard grading system.

Your grade point is 7.0 means your grade is B-

There is total 9 grade i.e A,A-,B,B-....

This depends upon the person having highest and person having lowest marks in the exam .

Suppose out of 100 and student having highest 6p marks and a student having lowest 50 marks then the highest one get A garde and accordingly grade were allotted  to the entir class.

Feel free to ask

Good Luck..
