Take a look at the Total column in your gradebook. You probably have good intuition as to whether those grades are correct or not. If not, or if you'd like to get ahead of any potential problems, consult this handy checklist.

If you see…

Assignments graded "Out of 0" points, do not enter points for these. Canvas will count any points awarded over “0” as extra credit (you might also exclude these from the final grade).
Extremely high total grades, you may have awarded points on a different point scale for some assignments (e.g. given 100 points to an assignment worth only 10 points). Make sure to edit the assignment to make the “points possible” align with the points you awarded.
Missing assignments, Canvas will treat the assignment as “excused” unless you explicitly enter a grade. Also, remember that Canvas can message groups of students who’re missing certain assignments.
Grades that don't reflect student performance, check your percentages and point values on the assignments page (e.g. the 100 point Roll Call Attendance assignment may dominate the grade)

As a final exercise, use the Student View tool to create a Test Student. Give them all A's. If the Test Student doesn't get an A for their total grade, check the common errors above.</p?
