How weighting is used to calculate grades is not always clearly understood. This article provides a clear explanation of the same so that Teachers can use it as needed.

- Under the Weighting section, click on Go:
- On the Weighting Setup page, select Yes for Use Weighting option, give the percentages to various categories and click Submit:
Note: The sum of the percentages/weights has to be 100.
In the above screenshot and the rest of the article, we will be taking the example where there are three weighted categories: Homework, Paper, and Test. Each is weighted 30%, 20%, and 50% respectively.
Below is an example where a Student has gotten certain percentages for 2 categories and then, his score has been calculated:
The figure above illustrates that a student's average for the Homework and Test categories was 60% and 70% respectively. Since there is no score for the final exam currently, that category will not be used in calculating the student's average.
The weight of each category used is multiplied by the student's average for that category. Those products are summed together and divided by the total of the weighted categories in use (80% as pictured above). In this example, the student has earned 53% of a possible 80% for an average of 66.25% as shown below:
How this percentage grade converts to a letter grade is based on the teacher's grading scale.
This method of calculation accounts for the fact that one assignment is worth more than the other, as opposed to an average of averages, where each assignment is worth the same.
This is how the overall weighted grades can be achieved.
