I started by randomly opening the book and reading. If I, knowing the subject, cannot understand what the author is saying, I believe that students would have problems. The author used many acronyms. I got stuck on "QAD." After about 1/2 hour of my searching through the text, I found what it meant: "QAD" = "Quick And Dirty." I did not select that book for my class. --Bob
