The way your gradebook calculates course grades depends on how you have set it up. For more about setting up the Gradebook, see ARCHIVED: Using categories and weighted grades in Gradebook. The following examples illustrate how the different choices in Gradebook Setup will affect how students' course grades are calculated.

## Displaying grades as percentages with no categories and no weighting

In this example, the instructor has set up the gradebook with no categories and no weighting.

Title Grade (%) Item value (Relative weight)
Exam 1 75 1
Final Exam 92 2
Quiz 1 93 0.5
Final Project 83 3
Midterm Project 70 1

The course grade is the sum of all the grades multiplied by their respective relative weights, divided by the sum of the weights.

## Displaying grades as percentages with simple categories and no weighting

In this example, the instructor has set up the gradebook with simple, unweighted categories.

Category Title Grade (%) Item value (Relative weight)
Exams Exam 1 75 1
Final Exam 92 2
Quiz 1 93 0.5
Projects Final Project 83 3
Midterm Project 70 1

As in the example with no categories, the course grade is the sum of all the grades multiplied by their respective relative weights, divided by the sum of the weights.

With simple categories, the instructor is able to see the student's overall percentage for each category, which is calculated in the same way as the course grade. For example:

Total (Projects): 79.75% [(3*83+1*70)/4]

However, these category percentages do not affect the student's grade for the course.

## Displaying grades as percentages with weighted categories

In this example, the instructor has set up the gradebook with weighted categories.

### Category Exams (70% weight)

Title Grade (%) Item value (Relative weight)
Exam 1 75 1
Final Exam 92 2
Quiz 1 93 0.5

Total (Exams): 87.28% [(1*75+2*92+0.5*93)/3.5]

The total percentage for the category is the sum of the grades multiplied by their respective relative weights, divided by the sum of the weights.

### Category Projects (30% weight)

Title Grade (%) Item value (Relative weight)
Final Project 83 3
Midterm Project 70 1

Total (Projects): 79.75% [(3*83+1*70)/4]

Overall course grade (Exams and Projects): 85.02%
