This book is a good preparation for the patent for three subjects: French, mathematics, history and geo - the Art History test is presented on two pages, but that's all. Each chapter has a reminder of lessons, corrected exercises including patent type of timed exercises. The book is well presented, colorful, fun to read, although a little too thick (it will be difficult to answer directly in the spaces provided for this purpose, because it is very dense). The answer is clear though very short and beware it is not detachable. Overall, I am satisfied with this book.
