The test
These schools each run their own test or share a test format, so the details below name the school or area they apply to. Each detail is labelled with where it comes from.
- Reported
- Slough, from the September 2027 test: two papers of about 50 minutes in one session, Paper 1 English comprehension and verbal reasoning, Paper 2 non-verbal reasoning and maths. Wirral: two papers of about 50 minutes on one day, Paper 1 verbal reasoning, Paper 2 maths and non-verbal reasoning; the Catholic grammar schools set their own tests.
- Reported
- Bexley: two multiple-choice papers of about 50 minutes with a mixture of subjects, weighted verbal 50%, numerical 25%, non-verbal 25%. Bournemouth and Poole: the new test is announced to start with the September 2027 sitting (for September 2028 entry), and one source describes three papers of about 40 minutes (maths, English and verbal reasoning), but sources conflict.
- Reported
- Answers are multiple choice on a separate answer sheet, marked with one horizontal line through the box. There is no penalty for wrong answers, and scores are standardised.

How to prepare
- Practise filling in a separate answer sheet, so marking the right box becomes automatic and no time is lost on test day.
- Learn the verbal reasoning question types one at a time, then mix them. Vocabulary grows fastest through wide reading.
- For non-verbal reasoning, check one feature at a time (shape, number, shading, size, position, direction) and rule options out.
- Spatial questions (rotations, reflections, cube nets) improve with hands-on practice: fold paper nets and turn shapes on the table.
- Sit full mock tests under timed conditions only every week or two, and spend the time in between on the question types that cost marks.
