Each subject is broken down and presented on an easy-to-use fold out 'map'. The maps use spider-diagrams and flowcharts to provide a concise, authoritative revision accessory, giving the student an at-a-glance tool for understanding how the different topics within each subject are connected. The maps can be pinned to walls to make the revision process easier. Students will find that these maps are an invaluable aid in their research, in encouraging creative thinking and in providing solutions to problem questions.
