Three settings in the activity editor affect how your students will be graded.
The grading policy affects several aspects of grading, from the availability of feedback to the point deduction per attempt.
Points possible range from 0 (no grade) to 100 in integer steps. If you change the points possible after one or more students have already started the activity, there will be a slight delay as their scores are updated. Changing the points will properly scale any existing scores.
If grade categories are configured in your gradebook, you can use this menu to move the activity into one of these categories.
