The 11th Hour Series of revision guides have been designed for quick reference. The organisation of these books will involve students actively in the learning process and reinforcement of concepts. At the end of each chapter there will be a test including multiple choice questions, true/false questions and short answer questions, every answer will involve an explanation. Each book will contain icons in the text indicating additional support on a dedicated web-page. Students having difficulties with their courses will find this an excellent way to raise their grades.
