Description

grade_grades This table keeps individual grades for each user and each item, exactly as imported or submitted by modules. The rawgrademax/min and rawscaleid are stored here to record the values at the time the grade was stored, because teachers might change this for an activity! All the results are normalised/resampled for the final grade value.
