As a student, I struggled with this subject and especially the cousework and I found this book no help at all. It was too general and gave only basic help and techniques that you could pick up in class and for exams, even the book didn't seem sure how to direct a student. It was set out strangely and was not easy to use.
I was finally able to get a B in my coursework but no help to this book. If you need help in English Lit, this book is ok as an introduction and some of the basics but no more. If you feel you understand the subject a bit more, it will give you no further insight into the exam, so if you want to go a little deeper go and read criticisms on the poems and books you have been set.
