## Summary

The Cayley Contest is run by the University of Waterloo Centre for Education in Mathematics and Computing. It is a grade 10 paper of 25 questions in 60 minutes (150 marks), in the Pascal / Cayley / Fermat family. It is completely unrelated to UKMT’s Cayley Mathematical Olympiad. A student may write only one of Pascal, Cayley or Fermat in a school year.

## Context

Waterloo CEMC’s grade 10 paper — not UKMT’s Cayley Mathematical Olympiad.

## Guidance

### Parent advice

If you are in the UK, UKMT Cayley is a different contest run by UK Maths Trust. This page is the Waterloo paper. Neither paper qualifies students for CMO.

### Student advice

You cannot sit Pascal and Cayley in the same school year. Younger students may write Cayley instead of Pascal.

### Teacher advice

2027 Americas window 23 or 24 February; elsewhere 24–25 February. CAD $6 per participant plus order/shipping charges.

## How to prepare

- Work through past Waterloo Cayley papers — not UKMT Cayley papers
- Practise Part C integer answers from 0 to 99

## FAQ

### Is this the same as UKMT Cayley?

No. UKMT’s Cayley Mathematical Olympiad is a UK follow-on paper after the Intermediate Mathematical Challenge. This Cayley Contest is a University of Waterloo CEMC school contest for grade 10.
