Frequently asked questions
Must weights total 100?
No. The tool divides by their sum and shows the average of entered work.
How are ungraded tasks handled?
Omit them for a current average; enter zero to count an uncompleted task as zero.
Does this give a letter grade?
No. Letter thresholds and rounding depend on the course syllabus.
