Pascal, Cayley and Fermat 2027 — US schools

Pascal is for grade 9, Cayley grade 10 and Fermat grade 11. Prepared younger students may write up; nobody may write below their official grade. Choose only one of this three-contest group for the school year. The 60-minute individual contest has 25 questions: traditional multiple choice in parts A/B and integer answers 0–99 in part C, for 150 points. Schools choose paper or online answers, but both modes require the same in-person classroom supervision. Top-quarter scores receive Certificates of Distinction; school medals depend on the published cutoff and CEMC discretion.
