Mixing NC Levels and GCSE grades
It is not advised to have NC levels and GCSE grades in the same series, as the analysis for one set of grades will not work for the other. For this reason, it is not possible to import both sets of grades into a single series.
If you are using a mixture of NC levels and GCSE grades to assess students, we would suggest that you create two separate series for your year group, one for each type of grades. You can use the same pupil data and classes for both series but you will need to set one up to use NC levels and the other to use Grades.
