When setting up the gradebook using the Natural aggregation method and using weighted categories the choice of specific point values becomes inconsequential. It is also important to note that the course total is displayed as both a point value and percentage to students by default. To illustrate this, follow the example below.
This gradebook is broken into three categories, Quizzes, Participation, and Homework. The Quizzes category is weighted at 60%, Participation 20%, and Homework 20%. The various grade item point values for this gradebook add up to 100 points.
Initial Student Example
Here we see Katie Gaucho's grades for the course. Katie received 9, 10, 8 points on the various quizzes for the course and full credit on the rest of the grade items in the gradebook. This resulted in 94 points be awarded to Katie and a 94% percent grade.
The gradebook has now been changed so that each quiz is worth 100 points. This results in the course total adding up to 370 points.
Student Example - Changed Gradebook
With Katie receiving the same scores that have been scaled to meet the new 100 points quiz values, (90, 100, 80) Katie still receives a 94% total for the course. Despite the total points for the course changing from 100 to 370, the category weights weigh the scores accordingly rather than simply adding the point values for the individual grade items and result in the same percentage in both gradebook cases.
