Revise the unit enrolments and ensure all the GPA values are correct. This may also require that the GPA values in the Grades Table are correct. To check each Unit Enrolment's GPA, [edit the Unit Enrolment record](/home/paradigm-knowledge-base/student-enrolments/workflows/manage-unit-enrolments/edit-a-unit-enrolment-record.md), check the Academic Outcomes section and check if the **GPA** field has the correct value.

**GPA** field in a Unit Enrolment record

If the field is not showing the correct value or not showing any value at all, review your grade items structure via the **System** > **Search Grade Type** menu. Make sure that the `UNIT_GRADE` type items are set to the correct **Grade Points** equivalent. Refer to the [**Grade Schema**](/home/paradigm-knowledge-base/system-configuration/workflows/grade-schema.md) knowledge article for more details.
