Another graphic expression of the student's progress is given by the bar graphs at the bottom of the report ("History"). These represent the general extent of the student's mastery: the blue portion of each bar represents material that was learned as of the given assessment, the green portion material mastered in the Learning Mode since that assessment, and the yellow portion material belonging to the curriculum for the given level that has yet to be learned. When the bar is entirely blue, the student has completed the curriculum for a level or levels.
