I would recommend to all AS psychology students to purchase this book as soon as they start the course. I was not sure about some aspects of the course before reading this book, but it gave a detalied summary as well as diagrams (funnily enough) and has helped me to understand key areas of the course more easily. I would imagine it will be a great revision tool when i come to sit my AS exams in june. Excellent, well set out book which covers areas of A2 psychology as well and suitabkle for several syllabus'
