Query: There will be better books than this I expect

I've bought this book because I was taking the exams on September, 2009. When I read the book I got the idea that the exams were focused on the main aspects on Linux and aren't "tricky questions", you understand me.What an error.What is the process number of init??Many questions are of this kind, and you can imagine my deseperation when taking the exam. If you are planning to take LPIC exams, bear in mind that, besides you have Linux experience, you need to know such things in order to keep up with the questions of the exams. For instance, I am SuSE user, and the questions of debian package management were... How to say?? They question aspects of parameters of dpkg the very used to use know.
