If you have changed activity scores in the LTI Advantage LMS gradebook, your changes might be overwritten by manually syncing scores from WebAssign. To prevent this, edit WebAssign scores in the WebAssign gradebook.

After adding activity links from LTI Advantage LMS, your students' WebAssign scores sync to LTI Advantage LMS based on your settings. If needed, you can manually sync scores to LTI Advantage LMS.
