Happy New Year DeWayne.
I believe the following may be the solution you are seeking.
- From the front page of your course, please go to: Settings → Grades → Categories and Items → Simple View. You will notice that an aggregation method needs to be set for the course and also for each category.
- Set the aggregation method for the course to Weighted Mean of Grades. Set the aggregation method for each category (Quizzes, Assignments, Projects, etc.) to Simple Weighted Mean of Grades.
- Notice, that you now have the ability to set the weight - (the percentage) - for each category.
For a wonderful explanation of why each category total reflects the percentage of 100, please watch this brief video on Simple Weighted Mean of grades created by Humboldt State University.
Best wishes to you for a healthy, happy, and successful new year.
