The New Spec Revision Guides (2016 onwards) for Year 1 provide an in depth summary for the key content for all three OCR papers. Key confusions to avoid are clearly identified, the chief authors and their critics quoted, and a summary of possible future questions is provided. The guide interacts with the peped website which gives full answers to the exam questions, predictions for this year's paper, and further self-test revision exercises and activities. "This book is simply a must have. I can read it anywhere, even during class because it is light and easy to navigate." JM, Canterbury
