I haven't used it- it's from the seventies and, from what I can glean from Google, has accompanying Drill cassettes, which suggests it's a grammar based book with substitution and other type drills, designed to ram home grammar points. Do the unidts focus on specific grammar points, with rather artificial texts crammed full of examples? If so, it's likely to be a Direct Method type book, where you're supposed to fire off questions to get specific answers highlighting a specific grammar point. I could, howver, be doing the book an injustice. Could you put up a few examples or some more details?
