Contact & Corrections

Found an error? That's the email we most want to get. Tell us the page, what you expected and what you saw, and — if you have it — a link to the official source that says otherwise. We compare reports with the cited record and its date, population and definition. Confirmed corrections are published after validation; no response deadline is guaranteed.

Formula disputes. If your school computes a grade differently than a calculator assumes, include the inputs, result and relevant syllabus rule. We will check both the formula and the assumptions; a difference may come from either a calculation error or a policy the model does not cover.

Everything else — questions, suggestions, a page you wish existed: [email protected].

Email a correction. Include public source links; please do not send student records or other sensitive personal information.

See the review process for how reports are handled.
