However, in all fairness I must write two good things about this book. First, seeing all the conjugations and tenses of a verb laid out on one page is helpful in making sense of the various verb forms, especially in terms of keeping them distinct from each other. And second, this book provides a list of some of the most useful verbs that you can study as a beginning student of the language.
My advice is to examine your own personal learning style and ask yourself if you really need this book, because once I learned the rules of verb formation, this book did little more than gather dust on my shelf.
