I recommend this book to 100%. Very gradually, a large number of exercises well made and corrected on a CD shipped with. Ideal for seeing shaky bases in grammar or prepare contest of public administration. I would advise you, if you do not have the corresponding grammatical method (Le Petit Grevisse) of you also get (what I do) because there is no point of grammar or summary before or after exercise addressing a specific concept (normal is an exercise book!). It may thus be useful or even necessary to revise a little theory before moving on to the practice. Especially since for each fiscal year, a reference to the grammar method is done. It's clear and effective! I love! Usable by all!
