A weighted grade category is a way to group and organize different types of assignments or assessments in a gradebook, such as quizzes, exams, and discussion forums, and assignment. 

Each category represents a specific type of work that contribute to a students' overall grade.

Explanation- By assigning weights to different grade categories, you can determine how much each category contributes to the final grade. This means some categories may have a higher impact on the overall grade than others. 

For example, exams might be weighted more heavily than forums.
