To view your grades in any course, simply click on the 'Grades' link to the left of the screen (highlighted in purple below). This will take you to the User Report.
The User Report contains all of your grades for a course. In this area, you can also find the weights for each graded item, the scale used to grade, and any feedback your professor has posted to specific assignments.
Professors are not required to post their grades to Course Connect. If you do not have any grades on Course Connect, it is best to contact your professor.
Not all professors use the same grading scale or methods. Consult your syllabus for a detailed description of your professor's grading policies.
