This book has KS3 Chemistry (ages 11-14) completely covered, with a superb blend of crystal-clear study notes and indispensable practice questions for every topic - all fully up-to-date for the curriculum from September 2014. It's ideal for students working at a higher level (that's equivalent to what would have been called Levels 5-7 in the pre-2014 curriculum). In addition to the notes and questions, there's a section covering everything students need to know about 'Working Scientifically'. Answers to the practice questions are available in a separate book (9781782941088).
