How do I know your content is accurate?

We take every measure possible to ensure our content is standards-aligned and accurate. All of our content is written by subject matter experts and peer reviewed by another author. All of our authors are thoroughly trained on our high content standards for writing clear prompts and helpful explanations. 

We then also moderate all questions and conduct a thorough internal review before the questions are published. After questions are published, users can submit any issues or feedback they have from the question page, or email us at

Finally, we conduct annual audits of our questions where we re-examine every published question for issues.
