If you have changed activity scores in the Brightspace gradebook, your changes might be overwritten by manually syncing scores from WebAssign. To prevent this, edit WebAssign scores in the WebAssign gradebook.
Sync Scores to Brightspace
After adding activity links from Brightspace, your students' WebAssign scores sync to Brightspace based on your settings. If needed, you can manually sync scores to Brightspace.
