Exceptionally well structured. It covers all of the relevant material at exactly the right level. The images are well chosen and generally well integrated, although I often feel that images are used in textbooks to make it look good and that these are often a missed opportunity and should be referred to more within the text (as well as a label). I like the extension activities, the range of questions and tasks and the text. There is something for everyone. This is asuperb textbook - so well written that I am going to review the exam board I am choosing next year.
