Complete Psychology is definitely a book that all students should purchase to help with learning about the subject. It is very easy to follow and understand. I especially like the questions it asks throughout the book. This helps with remembering what you have read. Therefore if you have forgotten then you only need to go back and refresh your memory. This will be very useful during revision times for exams. The book is fairly large, not something you can carry around all the time but it can also help with assignments. It is quite expensive yet it is worth every penny you spend on it.
