## Setting an item as "Extra Credit"

Extra credit replaces grade item weight if the aggregation method is "Mean of grades (with extra credits)", "Natural", or "Simple weighted mean of grades". The effect of extra credit is different in each case, hence some confusion:

- Mean of grades (with extra credits): A value of 0 does nothing. Any other value is used to multiply the grade and add it to the total after the computation of the mean. This grade is not used in the computation of the mean, however, only added afterwards. Additionally, this cannot bring the category total over its maximum grade unless grades over 100% are enabled by the site administrator (since 1.9.5). This grade item is not counted either in the denominator used to compute the category mean.

- Natural: Extra credit is a checkbox, not a number. Normally, with Natural, the category's maximum grade is the sum of the maximum grades of all its grade items. If one of them is set as "Extra Credit", however, its maximum grade is not added to the category's maximum grade, but its grades will be. This way it is possible to achieve maximum grade (or grades over maximum if enabled by the site administrator) in the category without getting the maximum grade in all the grade items.

- Simple weighted mean of grades: Extra credit is a checkbox, not a number. The "Extra Credit" grades are counted in the numerator used to compute the category mean, but not the denominator. See here for more information.

To change a graded item to an extra credit item for Natural or Simple weighted mean of grades:

- Go to
*Course administration > Gradebook setup*. - Find the extra credit item. To the right of the item, click "Edit > Edit Settings."
- On the Grade Item page, scroll to the bottom and check "Extra credit."
- Click the "Save changes" button.

To change a graded item to an extra credit item for Mean of grades (with extra credits):

- Go to
*Course administration > Gradebook setup*. - Find the extra credit item. To the right of the item, enter a value into the multiplier field. This will multiply the grade of the item and add it to the category total after the mean has been calculated. A value of "1" will be appropriate for most extra credit assignments.

### Courses using *Weighted Mean of Grades*

The *Weighted Mean of Grades* grading method focuses on providing percentage weights to graded items and categories. Because of this, Moodle does not allow for Extra Credit within the course category.
