Query: Great book to pass the exam

I took PMP earlier this week and pass on the first try. This is a great book, easy to understand but it has its own drawbacks. My exam was really tough. I hardly had any math questions and all the exam questions were really lengthy with lengthy answers unlike the practice questions that appear as excercise and final exam. It was like mini reading comprehension on each question. So expect to see much harder questions that what is in the book. Good thing is that with PM experience and reading this book from begin to end, it will not be a problem to pass eventhough there will be many questions outside of this book. I don't know if the exam is getting tougher day by day or it was just my luck to see those kinds of questions.
