| Stage 1 | English | 30 | 30 minutes |
| Stage 1 | Maths | 45 | 45 minutes |

Paper formats are indicative and change from year to year. Always check the current arrangements with the school or local authority.
The Sutton Selective Eligibility Test (SET) covers maths and English. Most families start steady preparation in Year 4 or early Year 5, building accuracy first and speed later, then sit timed papers through the summer before the test, which usually takes place in September.
For maths, secure the Key Stage 2 arithmetic, fractions, ratio and problem solving before moving to the multi-step questions that separate the strongest candidates.
For English, read widely every day and practise comprehension, vocabulary, spelling, punctuation and grammar; selective tests reward precise word knowledge.
