How it works

Register — a parent, guardian, or teacher signs a student up and pays online. Pick a division (Middle or High School) and a subject track.

Get your test link — a personal, one-use test link arrives by email before test day, with three regional time windows (Asia-Pacific, Europe/Africa, Americas).

Compete — 25 questions, 40 minutes, one sitting. Correct answers score +4, blanks 0, wrong answers −1. Hard questions break ties.

Get your certificate — results within a week. Gold, Silver, Bronze, Honorable Mention, or Participation — every certificate carries a verification code any school can check at scibout.com/verify.

Awards each month

  • Gold — top 5% (verified live)
  • Silver — next 10% (verified live)
  • Bronze — next 15%
  • Honorable Mention — top half of the rest
  • Participation — everyone who competes

Percentiles are computed within your division and track, so you compete against your true peers.

Every month, all year

A fresh tournament every month — 12 chances a year to climb the tiers. Question pools rotate monthly, so every round is a new challenge.

Four subject tracks

Math

Problem solving from arithmetic ingenuity to algebra, geometry, and combinatorics.

Physics

Mechanics, waves, electricity, and conceptual reasoning — calibrated to each division.

Chemistry

Matter, reactions, stoichiometry, and laboratory reasoning.

🧬

Biology

Life science concepts, systems, and data interpretation.

Enter one track — or several. Each track is a separate entry with its own awards.

A tournament built for the AI era

Every test is unique

Questions are drawn from a large rotating bank and numbers are randomized per student — answer sharing is pointless.

Humans only

Bot and automation blocking, human-input analysis, and consented webcam check-ins keep AI agents and chatbots out of the arena.

Verified winners

Gold and Silver are confirmed in a short live verification round before certificates are issued — and every certificate can be checked online.
