Like all BSM books, their approach to teaching is learning through humour. This type of book is aimed at a student age group- partically the teens 17yrs-20yrs.
This book is great in the sense that it teaches you through humour, as the situation will always stick in with you, for example in the book it says "theres no need to wiggle the gear stick to let the examiner know you checked" and it shows a humourous image of the learner driver agressively yoinking the gear stick and handbrake, with the examiner showing an facial expression of "Thats annoying!!" It has these types of scenarios throughout every page and in every chapter, which can make learning to drive more fun, during my test one of the examiners said to me "driving is a serious matter, think otherwise and you might end up in a graveyard"
This book gets the message across to the learner driver effectively, its presentation as a visual aid is great, this book alone won't do the trick, official DSA books are the only ones you need, yes they can be boring, full of text but they have everything you need to know, if your serious about passing you won't care- Trust Me!
