Reporting a question error

If a practice question has a wrong answer, a misleading explanation, or an outdated guideline, tell us the page link, the question text, and what you think the correct answer is. A source (a textbook or guideline) helps us check and fix it quickly. You can read more about how our questions are written and checked.

Technical problems

For upload, generation, or export issues, include the file type you uploaded, the browser you use, and what you expected to happen. Screenshots of any error message are useful too.

Billing and subscriptions

Choose “Billing & Subscription” above and include the email address on your account so we can find your subscription. Our terms of service cover how paid plans work.
