Query: Meteocre level text

I was required to use this book as textbook. It really doesn't help much but if you're the type who doesn't like to sit in during college lectures of a course such as Differential Equations, this is the book for you. It is hard to understand the text for this math book becasue it might ask you to refer to something in the previous chapter. I would definitely go with the first edition of this book. It was much better, and I myself have used the first edition. It is easier to understand. I have not completely read the book, but from what I have read (most of it) I can atleast say that this is not the "best of its kind". Chirag
