The ISEB Pre-Tests are used by many senior schools to help with their admissions process.

Keystone tests are based on the ISEB tests and have lots and lots of practice activities and tests.

Start each of your practice sessions with the diagnostic test so that you target areas that you need to focus on.

Come back regularly to familiarise yourselves with the format and to improve your understanding and scores.

This website also has videos and notes on the aims of the tests and how it all works.
