Workbook, Understanding and Using English Grammar, 5th Edition 5th Edition

Perfect.

Good product, good quality

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.

I got what I was expecting for

Estoy realizando mi curso de inglés con este excelente libro de gramática. Es mucho man’s profunda de lo que me imaginé al pensar que ha sabia lo más básico en Inglés, trate ejemplos y ejercicios guía

I am using this book for a grad course in ESL. It is very easy to understand and a great overall reference for grammar.

Promptness and quality—thumbs up!

I use it for my ESL classes at college.
