For courses that use Pass/Fail grading, a Grading Manager would create a separate grade translation, grade category, and grade plan. Currently, we do not suggest adding a Pass/Fail to a regular grade translation.
There are a few reasons for this. First, in order to control whether or not Pass/Fail classes are included in a Grade Average, the Grading Manager to be able to tie the courses to a separate grade translation. Also, the grade translation does not support having two grades with the same scores.
