Contact Us

Send a question, correction or accessibility issue using the form below. Do not include your password, exam account information or other sensitive personal details. Messages go to the site administrator’s configured email address.

We review educational corrections against primary sources and update content when warranted.

What to include

For a content correction, include the page title or URL, the sentence in question and an official or other reliable source that supports the correction. For a calculator issue, give the four numbers entered and the result you expected; do not include a student’s private exam credentials. Accessibility reports are also welcome: tell us the device or browser and what control was difficult to use.

The contact form sends a message to the WordPress administrator’s configured mailbox. It does not create a public comment or account. Delivery depends on the host’s mail configuration.
