Having started learning Japanese by himself for several months now (regularly but not always rigorously ^^) I had no trouble advancing slowly regarding vocabulary and kanji, but I knew not sure how to go about it in terms of grammar. This little book is exactly what I was looking for: A book that focuses on the essentials and offers a suite of grammatical structures "ready to use" chacunes accompanied by several examples we translate to exercise on sentences 'simple' as well as complex. Personally, I'm satisfied. Thank you :)
