Query: A good book, but without a defined purpose.

Some books serve to improve grammar, others to improve reading comprehension, and yet others to teach spanish culture. This book, however tries to tackle so many different topics that it is not able to do any one of them very well. each chapter is divided into parts. many of the vocabulary words are things that a student at that level already ought to know. there is little taught about grammar in this book, however the workbook touches on some subjects, but only the easy ones. i would not recommend this book for a spanish class.
