    -examWf examWf  [ -grading grading ] \
    [ -total_points total_points ]

Defined in packages/xowf/tcl/test-item-procs.tcl

Return the grading scheme object based on the provided short name. In case the grading scheme belongs to the predefined grading schemes, the object can be directly loaded. When the name refers to a user-defined grading object, this might have to be loaded. We could consider some hints about the usefulness of the chosen grading scheme, E.g., when an exam has 40 points or less, rounding has the potential effect that a high percentage of the grade is just due to rounding. So, in such cases a non-rounding scheme should be preferred.

Switches:

-examWf (required, object)

-grading (optional)

-total_points (optional, defaults to "100")

Returns:

fully qualified grading scheme object
