Calculation of Grade for Unweighted GradeBook
The calculation of the course Grade in a course with unweighted categories or no categories at all is:
Total number of points earned by the student / Total number of possible points in the course = course grade.
Please note that the calculation excludes items that have not been graded, muted or hidden from students.
Here is an example. A student received:
- 5 out of 10pt on Assignment A
- 7 out of 10pt on Assignment B
- 98 out of 100pt on Assignment C.
His course grade will be:
(5+7+98) / (10+10+100) *100%=91.7%
Calculation of Grade with Weighted GradeBook
To calculate the Grade in a GradeBook that uses weighted categories, we’ll use an example of a course that has three categories, Category A (weight 30%), Category B (weight 50%), and Category C (weight 20%). The calculation with this example will be:
(student percentage in Category A x Category A weight) + (student percentage in Category B x Category B weight) + (student percentage in Category C x Category C weight) = course grade
If a student earns 70% in Category A, 85% in Category B, and 90% in Category C, the course grade will be calculated as such:
(.70 x .30) + (.85 x .50) + (.90 x .20) = .815 or 81.5%
Please note that the calculation excludes items that have not been graded, muted or hidden from students. This means that if a category doesn’t have any countable grades in it at all, the calculation will change. Once the graded categories are added, they will then be divided by their combined weight. If we updated our previous example so that the student has 70% in Category A, 85% in Category B, and Category C is left ungraded, the course grade will be now calculated like this:
[(.70 x .30) + (.85 x .50)] / .80 = .79375 or 79.38%
