4 problems · 90 minutes

The summit. Six problems, two days, the world watching. Train the ideas here; write the proofs with your mentor.

• 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.
