Frequently asked questions
How do weighted grades work?
Each category's score × its weight, summed. Homework 92% at 20% weight contributes 18.4 points. We validate that weights total 100%.
What if my weights don't total 100%?
We warn you — a 90% total means 10% of your grade is unaccounted for. Fix the weights or the grade is wrong.
Can I include ungraded items?
Yes — leave the score blank or 0. It shows your current standing with the missing work as zero.
Letter grade scale?
Standard US: A 90+, B 80+, C 70+, D 60+, F below 60. Your school may differ — check the syllabus.
