Thanks for your response. I worked through your instructions as best I could but Moodle does not appear to be able to do what I need it to do. It requires a weighting of each graded item and then adds all the weights together. I need a process that calculates the simple mean of X grades in a category and then applies the weight of that category just to the mean and only one time. Then it adds all the weighted means together. If it is there, I most assuredly missed it.
