Moodle grade book, adjust item weight to calculate finale grade

1. Log into your Moodle course page. On the left,  click  a "Grades" icon. 

2. In the "Grader report" window, click the "Categories and items" tab. 

3. Click the 'full view'. 

4. You can adjust the 'Multiplicator' to give weights to each item. 

5. You can go back to the 'view' window to check the student grades, and make sure this what you want. 

6. Before do this, I suggest you to blind the "course total" from students. Make sure the changes are saved. 

Note: The weights are mostly going to change during the course. So, I would do this final grade calculation at least in late part of the semester.
