Scores Synced to Canvas Are Incorrect
When using an advanced LMS integration, WebAssign assignment scores greater than 100% or less than 0% are synced to Canvas™ as 100% or 0%, respectively.
The Learning Tools Interoperability (LTI) specification requires this behavior.
If this happens, consider changing how your WebAssign assignments are scored to circumvent the limitation. You might also award bonus/extra credit points separately in Canvas.
