Dusty White's 'The Easiest Way to Learn Tarot'

I bought this book some time ago. What I liked about it was that the blurb said it focused on learning and using the tarot in a practical way so that readings were accurate, and not wishy-washy or ambiguous.

However, I haven't had a lot of time to go through it and just wondered if anyone here has studied with this book and what they thought of it, and if they have any advice on how to work my way through it. (Can it be done in 10 minute time slots, for instance, or is it better to set aside an hour and work through it. That kind of thing.)

Thank you. :)
