To track your progress in a course, enter the Progress tab in the top navigation. The progress page shows your grade on various assignments. At the top of the page, you will see your average score for each assignment type and will also see your current course total.
Note that the “average” is the percentage of points you have earned so far for a particular assignment type out of the total possible points for all assignments of that type. As you complete more of the course assignments, you should see your averages increase. You can find a breakdown of all quiz scores below the averages chart.
