Thanks for your reply. >
I had bought your book, and today received it. Your book is easy understand although my mother language is not english. But I afraid this book is not enough material for me to take the examination. Anyway it is a good book, it cover the whole requirement of the 70-155,70-156. I will study it by heart, and put it into by briefcase. When I waiting Bus, Lunch time and any spare time I study this.
