What to include
A few details help us help you faster. For calculator issues, tell us which calculator you used, the exact numbers you entered, the result you got, and the result you expected. For feature requests, describe what you are trying to calculate that the current tools do not handle. Screenshots are welcome if your email app supports attachments.
Before you write
Most grade questions are already answered on the site. If your question is about how a calculation works, check the grade calculator guide and FAQs first. If a calculator result looks wrong, include the numbers you entered and what you expected, so we can reproduce the issue. For questions about your official school grades, please contact your teacher or school directly, since we have no access to school records.
