This is a great book. I teach IB Chemistry in an international school in Thailand and my students have had their fill of books which all follow a bog-standard, well-researched, but ultimately rather bland format.
This book is great in that it gives a lighter format which presents sound facts in a light-hearted way so that students are likely to read a section and not realise that they have learned too much.
It is not, however, a replacement to a text-book - more an addition to a student's library or reading resources. I'm recommmending our school library get a copy or two of this so students can, with their finals around the corner, use it to consolidate information.
It's a good buy and there are other in the series covering statistics, physics and genetics.
A great buy and a bargain price!
