This is a great book packed full of explanations and exercises to practise the key aspects of each chapter. The book is split into sections including verbs, numbers, adjectives, adverbs, etc. Each chapter starts with the very basic concepts on the grammatical concept and builds on this with relevant exercises until the next step is introduced. The book is well-structured and builds up information, layer upon layer and methodically. All the answers are at the back. This "workbook" is excellent for filling in gaps of knowledge and for refreshing your French grammar, or for someone of intermediate level wishing to reinforce their grammar and to learn more.
