Questions before your first raid?

Do I need an account?

No. Public quizzes are immediately playable. We want the learning experience to come before registration.

How are answers checked?

Factual questions are reviewed against reliable references, and explanations identify the reasoning behind the correct option.

Are the quizzes free?

Yes. ApexRaid is a free knowledge publication and may later be supported by clearly separated advertising.
