    Avoid this book!

    I read this book when it was launched.
    First thing it's not for absolute beginners.
    Secondly I read this book for quick revision. But I found many errors in the book and I had communicated back to the publication house, but no one ever responded back.
    It is better be avoided. Instead I would suggest to go with Definitive guide of Tom White.
