A null sit is a decision that means the assessment attempt doesn't count and therefore doesn't contribute to the maximum number of attempts allowed. Record a null sit using the NS grade.
A null sit may also be referred to as "resitting as a first attempt".
The guidance below covers how to record a null sit and then how to undo the null sit in order to enter new marks and process a new result.
Note: if the student is already in resit and you need to change it to null sit instead then start by undoing the resit. For guidance see Undo resits.
