This Tool is a Checker, not a Grader
This tool checks your assignments, but is not the final grader of your work. The instructor will review your submitted assignments and assign a final grade.
Even if all parts of the assignment are green in the checker, that does not mean you will receive a 100% grade for your work.
You must still ensure that your work completely satisfies the assignment.
