You can choose the aggregation method that best suits your needs for calculating a final grade, or Course total in Moodle.
“Mean of grades” will calculate an average of all grade items and categories.
“Weighted mean of grades” enables you to assign weights to grade items and categories.
“Simple weighted mean of grades” enables you to use a point system to calculate grades.
The “Simple weighted mean of grades” aggregation type will calculate a student’s total score as a percentage of each graded item. In other words, each item is divided by the total possible points possible. All the item results are summed and divided by the total number of possible points possible for the course.
In this example, you only give 2 tests and a final for a grand total of 350 points.
|Test 1||100 points|
|Test 2||100 points|
|Final Exam||150 points|
The formula to calculate the Course total is: (((Test 1 score/100) + (Test 2 score/100) + (Final Exam score/150)) / 350) * 100
