The problem occurs if we drop the lowest grade and there are excluded
tests (because the student was sick), for example:
there are 4 quizzes, each with 10 points. The caclulations are set-up to
drop the lowest. Student A has:
4/10 no-grade no-grade 2/10
The 2 no-grade results are excluded from the calculation (via the grade
exception interface).
So this student should have 40%: 2/10 should be dropped and therefore
the total is 4/10 = 40%
It turns out that the system gives the student 6/10 = 60%
(It looks like the exclusion works correctly as far as the total points are
concerned but one of the no-grades (=0) is dropped.) The calculation
becomes correct if I change the excluded grades to be 10/10.
Grade calculation error when items are excluded & dropped.
