Title: beginners' level
Review: The few times I looked something up in this book, I could not find it. I presume it was not there because the verb form was rare or not the most common one for that tense. Unfortunately, that was what I bought this book for. However beginners may indeed find it very helpful. Once you reach an intermediate level, you will have to use something else.
