This project integrates economics and business studies at AS and A level. It combines a systematic and analytical approach to business with the application of a streamlined body of economic theory. An investigative approach is used throughout the resources in order to encourage students to take responsibility for their own learning. Real world problems are examined using the critical insights of both subjects to create an active understanding of the important concepts. The option books build on concepts covered in the "Student's Book". They give students the opportunity develop and apply theoretical knowledge to new and more complex situations. In particular they encourage students and teachers to pursue their own studies in their chosen fields of enquiry. The books are meant to be used during the second half of the A level course. The choice of option books determines which A level the students are prepared for.
