As you work through the graded assignments in a course, your scores will appear on the Progress tab of your course. The Progress tab contains a chart of all graded assignments in the course and below that, a list of all assignments and their scores.
Note: Only graded assignments appear in the graph and count towards your final score. Ungraded "practice" assignments are not shown in the graph.
The "average" columns show your cumulative average for all assignments of that type through your course. This will rise as you complete more assignments of that type.
To pass you will need a total score meeting or exceeding the "Pass" line between the gray and white sections on the graph by the course end date.
For details on individual problem scores within an assignment, see View Your Grading Details.
You can see your current grade in a course by clicking the Progress tab in the course.
All questions regarding grading and course content are best addressed in your course discussion forum. It is there that course staff can directly read and respond to your query.
Note: Most edX courses post their grading policy in the course syllabus. Both the syllabus and the discussion forum are available once your class has begun.
