You can set visibility restrictions for grade categories and items that control when the categories and items are visible in students’ Grades view. However, categories or items with visibility restrictions will still be included in the final grade calculations unless you also follow steps to Exclude a Grade Category or Item from the Final Grade Calculation.
Setting visibility restrictions for grade categories and items only controls their visibility to students. Setting start/end and due dates for course components associated with grade items, such as Content, Assignments, Discussions, or Quizzes, is handled from within the respective tool.
To remove visibility restrictions from categories or items, return to the restrictions tab of the hidden category or item and select Grade item is always visible. Then click Save and Close.
