This book is essential for all taking this subject. Philosophy is very confusing and hard to understand and many take RS as what i call a 'bird course', which they think they can fly right through with little work and get high grades. THIS HOWEVER IS NOT SO!!!
If you are interested in this subject and chose it for the right reasons then you will find this book extremely helpful. However if you are not willing to use your brain they the wording may seem confusing.
I bought 3 A level books, and this is by far the best. It contains notes no the side full of simplified explanations and quotes which are vital for your exam essays. The book covers a wide range of topics and if you are in Wales and are studying WJEC board there are no books for that board, but this one works great, showing how detailed it is.
If you find this book too complex or unhelpful then i sugest you drop your course because it is not the right subject for you.
