How do I hide totals in my students' grade summaries?
Instructors can hide totals in students' grade summaries. By default, totals are visible to students. For courses using weighted assignment groups, assignment group totals are also hidden from students.
If your course is using Multiple Grading Periods, this setting restricts students from viewing grades in any grading period, even if the Display Totals for All Grading Periods feature option is enabled.
