Book amateur side layout, it smells the small publication. But I would say "finally someone who speaks a bit of English verbs!" instead of grammar. The lessons are pretty good overall and very synthesized, allowing to globalize in the head, what I wanted. As against the impression is lacking, it is written a little too small for my taste. I had to lose an eye out lol And the exercises are not gradual at all in trouble. In full mid-year, I need a higher level and especially seeing the next lesson to get there. It's frustrating and discouraging. The parade, let the sentences too hard and come back when you have all the header elements. In short it is a bit anything but doable and lessons-sheets have really helped me anyway.
