Query: Worst Text Ever

I'm currently working on my Master's degree and this is probably the worst book ever written. Without a doubt I can say that I have never read such a confusing book. This book contradict's itself while placing concepts together that shouldn't be placed together. The chapter's cover too much information without clearly explaining any given example that goes along with a section. If you can, avoid this book at all costs. If I'm not reviewing clearly it must be that I just finished the last exhausting chapter of this book.
