We're over half-way through our first semester using Moodle. Unfortunately, many of our instructors have set up their gradebooks incorrectly. They're using different methods of calculating grades (some assignments graded on a 4.0 scale, some on points, some satisfactory, etc.). Extra Credit has been extremely problematic as well.
So suppose you were going to teach somebody how to use the gradebook from scratch. What aggregation method would you suggest? Extra Credit does not seem to calculate correctly if you use anything but "Sum of Grades" in your overall aggregation method.
The whole situation is very frustrating, and everything I'm seeing is that from 1.8 to 1.9 the Moodle Gradebook took a HUGE step backwards.
