The Simple weighted mean of grades aggregation method is best for people who use a combination of points and percentages. This aggregation type does not allow you to set a weight for items or the categories; it simply uses the inherent weighting you've established by setting different maximum point values. For example, a 75-point item is worth more than a 25-point item. If you want all the student scores added together and divided by the points possible to obtain a percentage, use this aggregation. This aggregation also easily allows teachers to flag items as extra credit, if that option is needed.
