I am about half way through this book at the moment and it has definitely taught me a lot. The explanations are clear, concise and direct. The excercise questions are graded from easier to more difficult, so you can approach the work from your own personal level of understanding. I would recommend this for a beginner to pure mathematics as some of the other books I have read are not as direct. This seems definitely more condensed and to the point and thus holds your focus more intently. Happy with the purchase.
