  2. Click the space inside the category

Move to Weighted marks

3. The grade item will move

4. A new column called "Weights" will appear. 

This is where you will determine the importance i.e. the weighting of each assignment compared to others within the module

Setting the weightings of assignments

  1. Next to each assignment, in the "Weight" column, enter any number to change its importance in the overall calculation of the module grade.  For example: for an assignment you wish to contribute 30% to the total module calculation enter 0.3 in the weight field alongside that item.
  2. Click on the 'Save changes' button at the bottom of the page.

Note:  0 means the grade for this assignment will not be considered in the overall calculation for the module.  1 means 100% of the grade for this assignment will be considered in the overall calculation for the module; 1.0 is the default, meaning that every assignment has equal importance and will therefore contribute equally to the overall module grade e.g. 10 assignments will contribute equally 10% towards the final grade.

Setting the weighting

If you have formative assessments that you don't want to appear in the gradebook as part of the total, create a new category for Formative Assessments and set the weighting of that category to 0. Then move any formative assessments into that category.  See  Grades 5 - How to Add Categories & Organise the Gradebook
