Every chapter in the "Students' Book" has a corresponding one in the "Teacher's Guides" and each chapter follows the same format. A suggested scheme of work is given for each chapter. Every practical is reproduced in photocopiable format so that books can be put away to avoid spillages. On the reverse of every practical are Technician Notes and Practical Teaching Notes highlighting key outcomes, hazard warnings, and essential equipment requirements. Photocopiable assessment tests in two formats - actual tests and answer sheets - at two levels are provided..
