This is a textbook / revision guide that is tightly linked to the Edexcel sepcification. Unlike Pearson textbooks, the language is student friendly, concise and yet deeply informative. The sections of the textbook are tightly linked to the exact wording of the specification and the disciplinary thought that students are expected to apply in exams. This is an excellent resource for students to use in class, at home and for teachers when they want to truly learn a specification quickly in a way that will support authority in the way they deploy subject knowledge in the classroom.
