In the grade book, we display student's scores in different colors to convey additional information about that score.
A Green score - indicates that the student achieved a score above the set passing percentage ("Test Pass") for that grade category.
An Orange score - indicates that the student achieved a score below the set passing percentage ("Test Pass") for that grade category.
A Gray score - indicates that the score for that assignment or test has been hidden and will not be factored in as part of the student's overall score.
Instructors, you will also see an additional color if you are manually entering or altering student scores:
A Blue score - will be displayed when a score is manually entered but the Grade Book has not registered that change yet. Once you refresh the page the score will no longer display as blue.
