It is a good idea at the end of the semester to look over your Moodle gradebook to make sure it is calculating grades correctly.
Here are some tips for avoiding common pitfalls before submitting final grades:
Gradebook Calculations
Check that your gradebook setup is consistent with the grading scheme for your course. By default, the gradebook is set to "Mean of grades" and will simply average any grade items together. In nearly all cases, additional set up is required. For example, you may need to update the aggregation method and add categories to organize your gradebook items into groups.
See these tutorials for help setting up your gradebook:

Setting up a Moodle Gradebook: Natural or "Sum" of Grades
The gradebook is complex and has many grade aggregation options. It is a good idea to spot-check one or two student grades to make sure they are calculating the way you expect them to. You can also view the same grade report that your students see by following the instructions in this tutorial:
Viewing Grades as a Student
Hidden Grades
You may have hidden grades in your course, such as a hidden assignment or a quiz whose scores you haven't shared. If so, by default Moodle will hide students' course grades also. Be sure to reveal any hidden grades or delete any unused hidden assignments if you want the course grades to be visible and accurate. Hidden grades can cause discrepancies between the calculated totals seen by you and those seen by the student.
Empty Grades
By default, Moodle will not use "empty" grades when calculating course grades—blank cells in the gradebook will be ignored. If students have not completed an assignment, and you expect a zero to be calculated in for that grade, you must enter zero for that item in the gradebook. Otherwise, the missing assignment will not affect the students' course grades.
Zeros can be entered directly into the Grader Report when editing is turned on in the gradebook. You can also update all empty grades for a single assignment at once by following these steps.
- Go to the Grader Report and click on the pencil icon at the top of the column for the grade you want to update
- At the top of the Override column, select All
Scroll down. At the bottom of the screen, click the checkbox to the left of
Perform bulk insert.
Empty grades and a value of
0 will be selected by default.
- Click Save. The page will refresh and any previously empty grades will be updated to zeros.
Overrides
Some grade cells in your gradebook may be orange rather than the normal gray or white. This indicates that a grade has been "overridden". Normally, grades in the gradebook are pulled in from the activity itself (e.g. the Assignment grading interface). Override grades are entered directly in the gradebook, and replace the grade that would otherwise be there. This is common and not normally a cause for concern. For example, if a student receives a scores of zero for a discussion forum, the recommended solution is to enter the grade directly in the gradebook.
One place in the gradebook where an override can cause issues is when a grade category total is overridden. Grade categories are calculated based on the grading scheme of the category, and the grades that it contains. If you override the grade for a category total, Moodle will, from that point forward, keep that grade as you have entered it and not continue to recalculate the category total when items within the category are updated. In general, it is best to avoid this practice unless you have a specific reasons for preventing Moodle from calculating the category total from the items it contains.
Quiz Grades
Some quiz grade visibility settings are controlled within the quiz itself. If your students are not able to see a quiz or exam grade, take a look at the post "My students can't see their quiz grades. What should I do?".
