When using Grade Weights in GradeBook Plus v2 (Moodle 1.8.2) we are getting a discrepency in the total grades.
For Example,
A course with grades for...
Final Exam - Weight 10%
Participation - Weight 25%
Quizzes - Weight 25%
Journal - Weight 30%
Project - Weight 10%
A student gets grades (before Weight)...
Final Exam - 90%
Participation - 90%
Quizzes - 98.33%
Journal - 98%
Project - 90%
The gradebook gives a total weighted grade of 96.75%
I calculate the total weighted grade as 94.48% for this student.
Some of the differences are as much as 8 percentage points off.
The quizes were not Moodle quizes. These are all grades entered by the teacher into the grade book.
Why is there a difference?
