This book presents the content of the GNVQ in a way that encourages students to explore engineering for themselves, developing the expertise and knowledge required at this level. As well as a clear and accessible text, emphasis is placed on learning through activities, and self-evaluation through frequent knowledge-checks. Practice questions are also provided, and will prove particularly helpful for externally assessed units. Much of this book is completely new - reflecting a major syllabus revision that has taken place, thus making this text even more essential for students following the full VCE/Advanced GNVQ or a single award programme. This book is the only advanced engineering GNVQ/Vocational A-Level title endorsed by Edexcel.
