Query: Advise that matters

Do not buy this book. My professor selected this title for our introductory class, but two days into the course students were asking for alternative textbooks to buy. The book fails, big time, in explaining basic concepts and uses terminology that for an introductory class needs to be explained. I also agree with the other reviewer mention about the excessive amount of "copying and pasting" from other books. A disaster. I wish I could give it 0 stars.
