What will be measured

Format: Hands-on: editor, mcq tasks. No trivia — you do real tasks.
Domains: Movement · Kill and yank · Search and replace · Macros
Duration: about 20 minutes
Levels examinable: L1–L4
AI policy: AI-free
Scoring: Correctness first; efficiency (time, keystrokes, steps vs an expert reference) adds a bounded bonus. Graders check outcomes, so any valid approach passes.
Credential: Module badge, valid 24 months. $29 per certification attempt; practice is free.

Standard mode (L1–L3 on your public certificate): email verification, focus/tab detection, keystroke timing telemetry, randomized parameterized tasks, server-side timer.
Proctored mode (required for public L4–L5): government ID and selfie check, webcam snapshots and optional screen share, reviewed only if a session is flagged. Recordings are deleted after 90 days.
Unproctored results are capped at L3 on the public certificate; you can book a proctored retake to confirm L4 or L5. Every certificate shows whether it was proctored.
Retakes: wait 14 days per module, maximum 3 attempts per quarter. Your highest valid level shows on your profile.
We never show raw keystrokes or video to employers. You own your results. Data notice
