Switching to natural weighting
From MoodleDocs
Background
If a course uses a weighted aggregation scheme, switching to Natural aggregation will likely result in undesired outcomes that are the result of a known bug. Specifically, your weights will all be adjusted to a sum of 100, and items or categories that used a weighted aggregation scheme in the original course will be marked as extra credit. As a result, it may be easier to recreate the gradebook from scratch, though it is possible to “fix” the outcome by following the steps below:
How-To
- Before you begin, be sure to record your item and category weights. You can find them in the gradebook's Setup tab or menu link in the “Weights” column.
- From the Setup tab, click the “Edit” drop-down in the “Actions” column for the topmost row (the category for the entire course) and then click Edit settings.
- In the “Grade category” section, click the Show more... link.
- Change the “Aggregation” drop-down to Natural and click [Save changes]. All weights will be reset to zero and any value previously controlled by a different weighted aggregation will be marked as extra credit (as evidenced by the + sign next to their max grade).
- Click the “Edit” drop-down in the “Actions” column for any item or category marked as extra credit and then click Edit settings.
- In the “Parent category” section, click the Show more... link.
- Uncheck the Extra credit checkbox and then click [Save changes]. Repeat this process for any additional items or categories marked as extra credit.
- From the Setup tab, check the box in the “Weights” column for any item or category you want to be weighted.
- Fill out the “Weights” fields with the weights you recorded originally and click [Save changes].
