Proof-based olympiad. The readiness gauntlet checks your ideas; mentors grade your written proofs.

• Scoring: 1 per correct · 0 per wrong
• Problems are sampled fresh from the bank to match the official difficulty curve.
• The timer is authentic. Flag problems and return; blanks are a strategic choice.
• This is the answer-only readiness gauntlet — full proofs are graded in mentor tiers.
