I need to calculate student average of large dataset using excel.
It includes numerical equivalent for several characters such as A+ = 4.25, A = 4, A- =3.75, B+ = 3.25 and so on.
Information on the thread
really helpful to me to get an idea.
But the above method is not working for it. May be that includes + and - signs with character.
is there any solution for that.
