The way the ECTS grading scale was introduced implies that students who had started their studies while the old system still was in effect will graduate with transcripts containing grades from both systems (i.e., both numbers and letters).
In all subjects, students receive a grade based on the teacher's final assessment ("standpunktkarakter").
In upper secondary school, a grade of 2 or better is required to pass a subject.
This scale runs: "G" represents the normal good conduct.
In some cases the scale is extended with + or - suffixes, most commonly "G-", to inform a student of a borderline status.
