I chose this rating because this book is what I expected. The corrected exercises found in the book must be purchased separately, which is why my bill is not better. Regarding its manufacture, it is printed in France according to a sustainable development policy. This book is practical, rich in advice and explanations, perfectly suited to the beginner Excel and makes learning to use this software very gradually, step by step. For most exercises, better yet have bases in management-accounting. In addition, some exercises can not be done without the support of a trainer. Serious work that I recommend to anyone wishing to form on Excel 2007 or 2010.
