Strict test rules
A working webcam is required — the test is proctored and takes occasional stills to verify it is you. Check your camera before you begin.
The clock starts the moment you begin and does not pause — start only when you have a clear, uninterrupted block of time.
You get 3 submitted attempts per monthly cohort across both Verified Top 1% Skill Tests.
Timer is server-backed; expiry triggers auto-submit.
Answers autosave, but scoring happens only on the server.
Tab switches, blur, copy, paste, inactivity, and session resumes are logged for integrity review.
Monthly Top 25 rankings are based only on Top 1% Skill Test performance: correctness, coding, time, integrity, and attempt efficiency.
The product uses neutral language: integrity review required.
