UnGraded Assessments
In general, the assessments made by students are given a (small) proportion of marks which count towards their final grade. The grading of these assessments (and those made by the teacher) is done in the background by the workshop module. Provided a submission is assessed three or more times, the module can make a reasonable estimate of each assessment's "worth". (For submissions which have been assessed only once or twice, these assessments are given the maximum "grading grade".) As this grading process is done at regular intervals, the number of ungraded assessments will normally be zero.
The function of this link is to force a re-calculation of the grading grades, the grades given to assessments. The teacher may want to do this when either of these two options is changed:
