Plus/Minus Custom Scale
The following exercise shows how to
enter a “nonlinear” custom grade scale
with all grade-break levels (including
plus and minus).
For a “linear” grade point scale, the
b reak point spread is equal as shown
in the following table. Note that the
point spread for each grade is 2.5.
G r a d e P o i n t s Point Spre a d
A + 97.5 –100 2 . 5
A 95.0– 97.5 2 . 5
A – 92.5 – 95.0 2 . 5
B + 90.0– 92.5 2 . 5
Non–linear point scales do not have
equal point spreads as does a linear
scale. The following table is an exam-
ple of a nonlinear point spre a d .
G r a d e P o i n t s Point Spre a d
A + 98.0 – 100 2
A 95.5 – 98.0 2.5
A – 94.0 – 9 5.5 1 . 5
B + 91.0 – 94.0 3
