This manual, aimed at the formation and development of grammatical skills, is a collection of 400 exercises with keys and a short grammatical reference. Due to the large number and variety of exercises arranged in the order of increasing complexity, the presence of keys and grammatical explanations, as well as the availability of vocabulary, the manual can be used not only by graduates of secondary schools, but also by a wide range of French learners in classes with a teacher (at school, university, courses) or independently. The manual is also recommended for preparation for the Unified State Exam in French (USE).
