They work on different systems, and so do some schools.

Here's my school:
4.0 - A
3.7 - A-
3.3 - B+
3.0 - B
2.7 - B-
2.3 - C+

etc....

Anyway, some schools give an A+ a 4.3, which is BS, but that has to be accounted for.

Anyway, a 2.5 is halfway between a C and a B, which are traditionally C = 70%, B = 80%, so 75%

A 70% by the same reasoning would be a 2.0
