Class Only students in Progression & Awards
Students enrolled as Class Only won't have the course credits counted in the progression calculations as long as the course result is '0 NO'.
As Class Only students are excluded from the Assessment Hub they will have the 'NO' grade added automatically so you don't need to do anything.
A student's Class Only courses will still appear in the Progression screens under the Course Marks Profile but the credits won't be counted in the calculations.
If you do come across a student enrolled as Class Only but the course is being counted in the calculations you can change the selection status to "Non-counting credit". Instances of this should be minimal if they appear at all.
