Cie Ess Igcse Bs Bk/Wl 3E (Essential Commerce for Cambridge IGCSE & O Level)

I wouldn't suggest this book for in-depth learning. As the title suggests, it is only the essentials of the subject. The hodder education book is much better and has better explanation. Dont buy this if you want a great book. This book is only good if you want to prepare for exams in a short period of time.
