Understanding and Using English Grammar, Workbook

As advertised, arrived on schedule

Ótimo Livro, bem didático e é conforme a descrição.

I've used the Azar grammar series for over 20 years and like the explanations and all the practice exercises, both written and oral. This new 5th edition appears to be just as good as all the other editions. I especially like the online exercises and quizzes. I can assign them and see how students are doing so that I know what I need to concentrate on in class.

please, no one can purchase...; because there is no use for competitive exams

My friend is very happy with the book, is helping the understanding of English.
