Support

Sign-in, password recovery and identity verification are handled by the hosted identity flow. Start at the login page. A signed-in candidate can update profile choices and end active sessions from the profile page.

Certifications are charged once each, so there is no subscription to manage and nothing that renews. Your account lists every certification you have bought, what you paid and when, alongside your payment and invoice history.

If a payment succeeded but the certification has not appeared, wait a moment and reload before paying again: access is granted when the payment provider confirms the charge to us, which can arrive a few seconds after your browser returns. A second checkout for something you already own is refused rather than charged.

Keep the attempt reference shown in the test or result URL, the set name, question number, approximate time and a screenshot that contains no password or payment details. This is the information a future support channel will need to distinguish a content issue from a scoring, timer or connectivity issue.

Questions and explanations can be unpublished or corrected after review. A source-backed challenge should identify the exam, year or set, question number, disputed answer and the official or other traceable source supporting the correction. There is currently no public submission channel, which remains a launch blocker.
