Bought this for my ten year old, as the entry tests for secondary schools in our borough are based on verbal and non verbal reasoning. These are absolutely fantastic practice tools and I cannot praise them highly enough. Firstly, the short length of these tests means that children learn to work within a timed framework, without becoming bored or frustrated. The tests are separated into different categories, ie sorting and selecting words, anagrams etc, so it is easy to identify your child's strengths and weaknesses and act accordingly. My son really enjoyed using this book and the timed practice meant that he was not at all fazed when he sat our borough test today. Best of all, the company who produce these books are responsible for providing these tests to schools. My son actually found that many of the questions he had to answer for his test were exactly the same ones in this book. I have seen many books in this category, and this is the most accessible and useful by far. A must buy!
