This title covers the revised National Curriculum 2000 concisely; 21 short, clear topics focus on each strand of the Programme of Study. A 'What You Need to Know' summary followed by a 'QuickTest' exercise consolidates and tests information at the end of each topic (answers are provided). Each topic has a set of National Curriculum Test-style questions (written by the Science Test authors) to ensure thorough preparation. Assessment practice is differentiated in 2 tiers (Levels 3-5 and 5-7), enabling access and development for broad range. This book can be used for consolidation throughout Year 9, and/or at the end of the Key Stage for revision and practice prior to the National Curriculum Science Tests. Full answers to all the tests in this book are available free online.
