Challenge! Book 2 is highly recommended as a resource book for classes from Years 7 to 10 and for students who wish to develop their problem-solving skills. 

The Challenge! series of books contain the problems and full solutions to all Junior and Intermediate problems set in the Mathematics Challenge for Young Australians, exactly as they were proposed at the time.  

Most of the problems in this edition are graded to allow students to access an easier idea before developing through to higher levels.
