My idea has been closed twice. I will ask again for an easier solution.
In the old grade book I could set the weight for each chapter. e.g. I think chapter 3 should have a weight of 3 instead of a default of 5 but yet I feel chapter 8 should have a weight of 9. There are many reasons a teacher may wish to adjust weights. The answers I have been given are confusing at best and involve many steps. It should be easy to set each chapter to a default and allow instructors to adjust.
