Bought the book and the quality of content is a big step up from the outdated green Passbooks. The author has a very thorough knowledge of the civil service exams for T/O and C/R. The best value of the book are the test questions, and the difficulty level is on par with the past T/O and C/R exams that I had taken. I am definitely giving this to my friend who is interested in taking the next T/O and C/R tests. It never hurts to start preparing for the exam even if it's a few years from now.
