All trainee teachers in England and Wales have to sit numeracy, literacy and ICT skills tests in order to achieve Qualified Teacher Status (QTS) which permits them to continue or start teaching. This book focuses on the mathematics part of the test, targeting candidates who feel they have weak numeracy skills.
Practice, practice, practice. There are only two mock tests and they are slightly different from the online tests found here: http://www.education.gov.uk/QTS/Numer...
The questions are a little different but it doesn't hurt to learn a few new things just in case. It takes a bit of getting used to. What could have been improved is the way the working is shown. It's difficult to decipher what steps were taken to reach the final answer.
