How the exam works

  1. 1
    Start when you're ready

    The clock starts the moment you begin and keeps running even if you close the tab — there's no pause.

  2. 2
    Capture 5 of 6 labs

    Open each lab, exploit it, and submit the flag it gives you. Solve any 5 within the 3-hour limit to pass.

  3. 3
    Proctored for integrity

    Leaving the exam tab is recorded and factored into an integrity score printed on your credential — the pass has to mean something.

  4. 4
    Earn a verifiable credential

    Pass and we mint a signed credential with a public verify page and a shareable certificate — provable, not self-reported. Plus +500 XP.

  5. 5
    Miss it? Cooldown, then retry

    If you don't reach the threshold, a short cooldown applies before you can retake — so the credential stays meaningful.

Exam labs (6)

Solve any 5 of these 6 to pass. Once you start, the clock runs even if you close the tab.
