In this article, we'll have a look at extra credit assignments and assignment groups...

### Adding extra credit assignments

You can add extra credit assignments at the assignment group level and at the individual assignment level. You can also edit existing assignments/groups.

When adding an assignment or group, check the box to indicate whether they’re extra credit. (If an assignment group is set to *Extra Credit*, every assignment in that group will be automatically marked as such.)

### Grading extra credit assignments

Extra credit assignments are graded just like any other assignment. The magic happens when the assignment is included in the final grade calculation...

### Assignment groups

When you make an assignment group extra credit, every assignment in that group becomes extra credit. Whatever grade weight you give that group will be available *in addition to* the course’s 100 percentage points.

For example, say your extra credit assignment group is worth 5%. If a student gets a perfect score in all of those assignments, she’ll earn an additional five points on her final grade. So, if she gets 100% on her regular assignments, her final grade will be 105%. If she scores 90% on all other assignments, then her final grade will be 95%.

### Individual assignments

When you make an individual assignment extra credit:

- If earned, those points
*will increase*increase his grade - If missed, those points
*will not decrease*his grade

For example, say your "Quizzes" assignment group carries 10% of the course. You have ten 10-point quizzes and one extra credit quiz—also worth 10 points. That gives you 110 potential points out of 100. What happens when a student takes all 11 quizzes?

If he gets 90 out of 100 on his regular quizzes, and scores 8/10 on the extra credit quiz, he’ll get 98% in that assignment group. If he gets 100 out of 100 on the regular quizzes and 5/10 on the extra credit quiz, he'll get 105% on the assignment group.

Consequently, that group will end up contributing 10.5% to the final grade—instead of just 10%. If he otherwise aces the course, he’ll get a grade of 100.5%.
