No offense, the authors of this book are sure great chemist... However, this book is the most boring book on the planet... It is printed in about three colours, each page is filled with text and there are barely any pictures... And also, the answers to the exercises in the book are not in the back of the book, but on the cd which is attached to the book... The only, according to my opinion, useful and good thing about this book is the glossary which quite in depth explains different chemist-terms. I studied IB from 2007 to 2010 and this book made chemistry a HELL! So, buy the book by Catrin Brown and Mike Ford instead, it kicks ass for being a chemistry book...
