Please mention "Grade Calculator" in your first message so we know which site you are writing about.
Before you write about a grade…
- We can't change, appeal or certify any grade — only your teacher or school can do that.
- If a result looks wrong, double-check the weights in your course syllabus first; a wrong weight is the most common cause.
- If you believe a formula on the site itself is wrong, tell us the numbers you entered and what you expected — that helps us check it the same day.
