Frequently Asked Questions
What happens when my weights total less than 100%?
The weighted average uses only entered assessments. For example, 80% on work worth 50% of the course gives an 80% completed-work average and contributes 40 percentage points to the final grade.
Will the result match my official course grade?
Only if the entered scores and weights match its rules. Dropped assessments, extra credit, grade curves and letter-grade boundaries are not applied.
Are assessment scores saved in a profile?
No. There is no student profile, and these scores are processed in your browser without upload or application storage.
