The title is comletely misleading. This is a book of grammar exercises. Chapters are entitled Nouns", "Verbs", "Correct Punctuation"- you get the idea. Even the sentences and examples used in the grammar are unrelated to business. The only bow to business is in the last 20 or so pages which are about letter writing, telegrams (!), memos and other business writing forms. As far as I can see, there is no conversation skill practice at all. I gave it two stars because it you want a succint little grammar practice book, it's ok. But go elsewhere for business and/or conversation.
