Query: Waste of time and money

This is the worst book that I bought in my life. I knew that it is bad but I was imposed to buy for my class in the University.Beside it is expensive $75.00!!!!!!!!!!!!!, it is worst than any book that worth $10.00!!!!!!!!!Same sentences are repeated many time and the book is easly tears after a while.I would to throw the book after finishing the course, rather than keeping it.It is a nightmare!!!!!!!!!!!!!!!!!!!!
