Each book is targeted at a specific year group, so before buying check that you have the book appropriate to your child's age range.

Each mental test consists of 5 second, 10 second and 15 second questions. There is a question sheet for the adult and a photocopiable answer sheet for the child. Answers are provided in the book.

I would highly recommend this book and others in the series to any teacher or parent who wishes to aquaint their child / children with the vocabulary and the range of questions which appear in the optional SAT's test.
