An excellent way to increase your French vocabulary after about a year of college French or two years of high school French. If you follow the Common European Framework Reference for languages I would say the level of the book is A2/B1. The main benefit is that it never uses English translations, so even the explanations and illustrations are entirely in French. My only criticism is that the answers to the exercises are published separately and not included in the back of the book. However, if you re-read the introductory paragraphs for the new vocabulary, you should be able to check your work without resorting to a glossary or dictionary. Some educators even prefer not having the answers too readily available as that could discourage you from trying to figure them out for yourself.
