As a public school teacher in Massachusetts, I find this book almost unusable. I make use of it only as outside-class reinforcement for Spanish speakers in my classes who need to acquire ONLY basic speaking skills quickly. Keep in mind, however, that the Spanish/English version contributes to a dependence on the student's first language, and its format & layout can be confusing. There aren't enough practice exercises in general, and it doesn't address any academic skills such as punctuation, capitalization, writing longer sentences/paragraphs or reading comprehension. Its saving grace is the pre-laminated reference sheet for common vocabulary and phrases. It would benefit from an accompanying CD or tape for speaking practice and reinforcement at the very least. Take care before you buy.
