Technical Errors

If you encountered a technical error, please provide as much information as possible; including what device you are using, operating system, browser, type of screen (touch screen?), and any error messages.

Before adding a comment, please make sure you read the question again. Perhaps this question asks what you should not do or which statement is false?

Do not overlook the reversing effect of negative words. You should also take note of absolute words like all, none, always, never. They often make an alternative false. Never rush your selection. Consider all the answers to make the best choice.

You should know that more than 9 out of 10 reports we receive are no actual errors. They are mistakes like the ones mentioned above.

Leave your e-mail address! We will try to help you with any misunderstandings. E-mail, however, is not required, so do not enter a fake address. It may cause the system to block you from further access.

Wrong or Old Information

Still think you see an error? Sometimes we make mistakes. Sometimes things change. Just let us know. Real errors will be fixed as soon as possible, usually within 24 hours.

Your help to make this a better website is greatly appreciated!

If you don't see a change within 24 hours, you can assume that the question or answer you reported was not an error.
