The schools we’ve had experience with grade on a 4.0 GPA system but with the decimal plus, e.g., 3.999. Both our daughter and her co-valedictorian had taken advanced placement classes as well, which were graded on a 5.000 scale, so both girls actually achieved about a 4.600 GPA and were ultimately separated by only something like 0.001 point.
My son’s school grades the way your daughter’s school grades.
However, he’ll get a 4.0 with barely a 90% in the class, and there are kids with almost a 100% in the class who also get a 4.0. That’s what I don’t like.
I know they’ve had multiple valedictorians at his school with GPAs around a 4.6 or higher also.
