This method of review is very well written and organized. The 3 materials are one after another with the bottom of each lesson keywords whose clear definitions at the end we can find. The end also includes a bibliography of important theorists (management and economics). Really well done. The book concerns the programs of two years of BTS in management, law and economics. It is just a pity that the opening takes place up and that the plugs can not come off because the book is a little big.
