How do I add or delete grades/results for a pupil?

Make sure that you're using the series that you need to remove the grades from.

Go to Admin > Edit Results

If you are adding a grade/result, find the pupil on the left and look across the subject columns. Click on the relevant cell and use the dropdown menu to select a grade. 

If you are removing a grade/result, click on the relevant grade and use the dropdown menu to select the 'blank' value,

Alternatively, If you want to remove grades for a subject from all series for a single pupil you can use Admin >Edit Pupil. Click on the student and a panel will appear on the right hand side.

In the Results tab, click on the subject you wish to remove grades from and use the buttons at the bottom to choose to remove results from 'This Series' or 'All Series'.  

NOTE: if you remove from All Series this is irreversible and will remove all records for the subject for that student.
