I came across Tony Buzan's work in 1990, when I had just started studying for a degree whilst working full time. It was not until I read this book that I actually learnt how to learn quicker, more efficiently and be able to access that knowledge easier.
Throughout this book you are given examples, explanations and tests that you can use to prove to yourself within minutes that what you have just been told works. In fact, not only are you told at the start how incredible your brain is and how much you already know, but this book then helps you proves it !!
Each chapter could be a book in its own right, however the aim of this book, quite rightly, is to give you 80% of the benefit for 20% of the effort.
