Professional English in Use Management with Answers 1st Edition

This book is useful if you targeting only management English and its level is high intermediate. As an ESL teacher for business executives, I am always loooking for good vocabulary books for business but most of my students need a broader spectrum book which this is not. Also a little lower level would be better as many business professionals do not come to the US at a high intermediate level. I use it as a resource book but not as a primary book for student use.
