This is the common WAEC-style scale used by many Nigerian secondary schools. A score with a decimal, such as 74.5, is graded by its cut-off (74.5 is B2 because it is below 75). Your school may use a different scale, so follow your own.

What the grades mean

  • A1 to C6 are credit passes. Many schools and later exams treat C6 (50) as the lowest credit.
  • D7 and E8 are passes below credit level.
  • F9 is a fail.

Using your own scale

The table is a common example, not a rule. Your school can set its own bands and remarks. What matters is that the bands have no gaps (a score of 44.5 must land somewhere) and that every teacher uses the same scale. StudyPat lets a school set its grading scale once and warns about gaps. See the guide to computing CA and exam results.
