I pre-ordered this book for about $70, which I thought was a good deal especially for a hard cover textbook.
The book seems pretty sturdy and would be good if you needed an expensive large paper weight, a heavy object to throw, or to fill up a shelf with random textbooks to delude your friends into thinking you're smart and actually read and understood the book.
The book does an awful job of explaining everything and anything, I'm pretty sure I learned more from checking the answer of a problem and working backwards than actually reading, my gosh it's horrible. If it weren't for my professor who gave us worksheets to do and showed how to do it I'm sure I wouldn't have done well in my class.
I would give two stars because of the great price, but this textbook material is just awful and "I HATE IT". Of course I'm being bias and this textbook could work for others, but I found this textbook to be the worst of all textbooks I've had. If this textbook is required for your class I would just recommend renting it and sending it back for another poor soul to go through its torment.
