I am soon to attend college to do a two day course on portable appliance testing that is the practical and theory side of the course later I have to complete an online test of my knowledge so I thought I would get ahead of the game by studying before I go to college and sit the test. The book is exactly as described in that it covers all the kinds and types of typical qusetions that you are going to be asked. It is well written and throughly researched as it gives you a step by step guide through the different parts of the examination, if you have been listening at college this is a refresher to the actual exam, not the actual questions by ones very close to the ones that you will be asked. I recommend it to first time learners and as a refresher to other electricians or managers.
