If categories are not weighted, grades are calculated by multiplying each assignment's percent grade times the assignment's gradebook points, then summing these points across all assignments. The final grade equals the total points earned divided by the total points possible. In this scheme, categories serve solely to organize assignments in the gradebook.
If categories are weighted, you will enter a weight for each category. To calculate grades, gradebook points for assignments within each category are first summed, and a percent of points earned for the category is calculated. Then each category's percent grade is multiplied by the category's weight to determine each category's points, which are summed. The final grade equals the total category points earned divided by the sum of the category weights.
To weight your categories follow the instructions below.
