I think it is a great help for students and a life-saver for those who do not have good teachers and therefore need to study themselves, like me. I learned more out of the book of Peter Stimpson and the CDs that come with it than I did in 4 months of A Level at school, or from tuition centres here, after which I switched to studying myself. But I am truly disappointed as well since the author says in the book that the CDs had answers to "all of the activities, case studies and essay questions in the book along with suggestions for further reading". But well, they don't. They don't have answers to all essay questions as I am just discovering, nor does it answer any of the review questions at the end of a chapter. Though there are exceptional answers to case studies, etc. Sometimes I think I could use more explanation of the points referred to in answers cuz I don't clearly understand the meaning. I have to research a lot. The CDs are nevertheless a great help since I can write my answers and then compare them with the author's answers which give me so much information and guide me in writing superior quality answers. My teacher's answers used to be no better than mine but these are awesome. However, I do wish I had been given the right information regarding its contents and had not been misguided. Because that's not what I expected of the authors and is very disappointing indeed.
